View Full Version : swivel bucket seats and belts

Who knows if standard bucket seat belts work with swivel bucket seats. If not what is the difference in them. :confused:
Pictures would help.

No, the belts are different and so are the outer rear seat mounts. I'll try to snap some swivel/bucket belt photos when I get home this evening.

Don't want to step on any toes but I was working on my swivels recently and saw the thread so here goes. Three pics of my '73 swivel belts. The center belts have the rigid plastic sleeve that holds up the female end. They bolt to the center hump behind the console. The outer male end bolts to the outer frame behind the seat. I hope you can make out the pics. The Fisher body manual has good details (pages 470,472). I have no idea how this relates to standard buckets, but maybe the pics will help.

99% of the time when someone pulls the swivel seats they don't grab the belts. People just don't realize that those belts are needed with those seats otherwise it's not setup correctly. It took me a few years to find a few replacement belts for two cars that had them cut by previous owners.

Here are the photos I mentioned earlier. I ran across a monte that had swivels at some point in time and someone didn't get the belts nor the mounting hardware from the floor pan.

This is the swivel mounting bracket for the passenger outer seat track-rear (welded to the floor and secured by a torx bolt that I could not get loose) and the hole at the back of the photo is the swivel seat belt mounting hole (uses a torx bolt as well).


Undercarriage mounting hardware for the seat belts: both brackets for swivels including the swivel seat outer track and the bracket on the left is the swivel belt bracket or if the bracket on the right is for regular bucket belts without the swivel option.

Now for the seat belts...

Here's a photo of the regular bucket belt (driver side) in my 77 and the floor pan set up for regular buckets (notice no swivel bracket and no extra hole at the rear of the pan).

Seat belts side by side - granted these are not cutlass swivel belts, this is simply for reference.

Here's the cutsheet from Fisher Body 1973 version

great thatnks for the info. so if I want swivel bucket seats I need the belts and mounting bracket to make the switch from a strato. I am just looking for a little more support in the seat and the swivel looks to give extra support.

Piazza - I probably posted to many photos to answer your question but figured I'd post what I've come across in my seat/belt research.

ZodiacblueS - thanks for the photos of your belts and cut sheet, I wondered what was in the 73 manual and what the difference is between 73-77 belts, cool.

05-19-2011, 11:12 AM
Hey we're all in this thing together. :confused:

05-19-2011, 11:19 AM
Absolutely! :) As Nick stated most of the time people grab the seats and leave the most important pieces behind (belts and floor mounts/retainers) IF they're doing a conversion. Before my research, I thought you could do a direct swap from the strato buckets to the swivels. Uhhh, no...live and learn, Ha!

05-19-2011, 11:28 AM
Great info. I guess you can only do a direct swap to Salon seats from Strato

The 73 belts are lap belt only where it mounts on the floor and the shoulder belt tucks in along the headliner and does not retract. The 74-77 belts have the integral shoulder belt that meets at the lap belt male end buckle and has a retractor mounted on the ceiling. I think that is the difference. I also think the floor retractors are the same for all the years excluding the sewn on shoulder belt. Those Malibu and Monte belts are the same as the respective Cutlass belts. I have a Monte Carlo swivel seat driver's belt mounted in my car and it was the same as the Cutlass belt I replaced but in nice condition of course.

Piazza - I believe that is correct.

Dave -Funny, I said to my self, the 73 belt looks different from the rest, another piece specific to 73. :)

FYI-Bench seat uses the same belt on the retractor end as the strato seats.

Also note, that swivel buckets were only available from 1973-76.

While on the subject is there any way to tighten up the free play on these swivel seats when locked in place? Feels like I'm doing The Twist. Been that way since new and its annoying. Passenger seat is nice and solid.

I found some seats for $200 with the seat belts. They are even in good shape :D. I wonder what the fisher body book says about a 74-77

My drivers seat swivel on my 75 was loose as well.... twisting and turning as I drove... I tore it apart and welded the notch area and then used a dremmel to grind it back down for the proper fit. Nice and tight now.

I am picking the seats up Saturday is their any advice of what I should look for when buying these seats?

06-23-2011, 12:04 AM
I'd say check the mounting feet to see if they are all not weak from rust. That could be the deal breaker.

Some small things/details...
Check for the seat belt loom mounts on the upper and lower sides. Sometimes the mounts rip out and the holes in the bucket seat shell are ruined and need repair. If the actual looms are missing but the mount isn't ripped out of the buckets then you can get the looms on evilbay for $10 in black. Also check for the black swivel knobs. They are hard to find but have seen them on evilbay from time to time.

For the seat belts you should have two upper mounting bolts that are not T50's but a regular 9/16 bolt, gold in color. I think these bolts are rated for a collisions. Then for the lower a single T50 bolt.

I think the drivers side may have some wires for the ralley pack seat belt buzzer, and the 74's will have the starter disable switch as well.

Lastly the lower seat belt floor mount is a piece of angled steel. This too gets rusty and weak so make sure it's not flimsy.

Oh and the swivel bucket "twist". :D

Thanks for the info.
I will check that out

I picked them up this week end and they are in great shape. They operate smooth and no rust.

I do need one swivel lever, and the plastic that covers the seat belts at the floor are falling apart. If anyone has these parts let me know?

Also can I change out the seat belt webbing from my existing belts and install this into the swivel mechanism.

To convert a 77 442 from bucket seats to swivel buckets, you will need to fabricate a hole for the swivel seat belt bracket and bolt in the floor pan. You will also have to fabricate a steel plate with a bolt, for the swivel bucket seat rear leg to fasten it to the floor pan.
