Suburban rear seats and tracks, any info?

[aerotruk63]

Did you recess the electrical tracks into the floor?

The guy I'm trying to find original 63-66 GMC seats for would like to have the drivers and a reversed 2nd row 39" seat touching back to back and the 3rd. row 56" at the rear position. Give the rear area a limo feel. We joked about installing an original wheel and tire with a hubcab with a round plexiglass top to use as a coffee table between the two rear seats.Your track idea might help out in this application.

[dthela]

don't think there would be enough leg room. lay them in loose to try it. You could always use the unistrut in the original slots too. they do make assorted pipe clamps and angles that work with the unistrut system

Because I have a 65 suburban with barn doors I want to put two short 2nd row seats one behind the other so the seating can be accessed from the rear. Is this even possible, I don't see that type of arrangment in any of the diagrams.

[aerotruk63]

I was at a yard this week that had dozens of old school bus seats. I measured the base and their 39" approximately wide. Same width as the smaller rear seat in the rear or the drivers seat. Cheap to buy, easy to modify, if your not going for original. Now on this originality thing, I can't see GM opting to have suburban seats made in house and these seats sure are fabricated in the same manner as school bus seats. So I sent off an email to Blue Bird one of the oldest school bus manufactures in the States. Maybe they'll respond with who supplied them seats back in the early sixties.

rossboss saw a school bus picture of a suburban set up that way.

Yes, if you have two of the 2nd row seats you can accomplish this. The mounting should be the same since the 3rd row seat is able to be bolted in the 2nd row position.

1963 GMC with tracks.

[Carryallnuts]

I was told that GMC had the sliding tracks and Chev the bolt openings. But I also know that they used whatever was at hand when building our trucks. I have seen burbs that had the truck style solid metal steel body mounts under the core support, instead of the vulcanized rubber ones. I would bet that there are GMC's with the bolts. Think about it, back then no one would question how their truck came from the factory as long as it had the 2 or 3 rows you ordered. It's only because of our addiction to these super cool trucks that we want to learn everything there is possibly to know. Look through the GM accessory booklet and see if, ordering with sliders or bolts was an option. Maybe it was

Did the 63-66 GMC rear seat backs come clad in vinyl instead of the painted ribbed steel? Seems the two front seats are steel backed however.

[dthela]

GMC's had bolts into holes in floor, chevy had tracks. I never used the unistrut, only a suggestion. I have seats out of a eddie bauer expedition buckets front, buckets center and rear 60/40 full width. left buckets in the s4econd row to the sides so i have a center "hallway", easier than tilting seats forward. I was howevwer going to use Caravan seats. But when the set of leather electric came up for $250 I couldn't resist!

Again, read the thread's progression before commenting. You are partly correct and partly wrong.

I'm pretty sure that no years had vinyl backed seats.

[aerotruk63]

The picture above with the vinyl covered back is from a 1966 GMC out of New York State and Bills Truck Shop in Ontario has a 64 GMC for parts, out of California, and it had a Vinyl back on it. Need to find another source. This is so interesting how GMC was different than Chevrolet in the seats.

[padresag]

you more than likely got more for the buck with GMC than you did with Chevrolet. like the guard under the rad

Seems that way doesn't it Ron.

[padresag]

had one of these sticking out from the base of the back seat that was stuck in the back of my suburban. the seat had come out of a panel and had been screwed into the floor

Here is the mounting bolt/spacer/wingnut on my 1961 GMC seats.
Also the seat cushion for your bum, pops out rather easy due to this
angled frame/detent/whatever you'd like to call it. These seats are heavy
so anything to lessen the load for removal

[aerotruk63]

What size Carriage bolt is it? 3/8" ? The head of the carriage bolt looks wider than standard, what is it's diameter. The wing nut looks like the wing nut that holds the air cleaner on the stud.

[padresag]

it is a 5/16 carriage bolt. I am also enclosing a picture of ,I don't know what to call it. It was used to fill one of those 7/8" holes in the rad support of a 62 GMC. must have been an orig installation by looks of it. it is 1 3/16" dia. perhaps you can find it in a parts book .

maybe it is one of those rare piece's that perhaps my friend in Mo. may be interested in for his rare truck

[aerotruk63]

That resembles a replacement frost plug without the rubber.
And don't change the subject Ron. lol

didn't know where else to put it and to grab your attention as I knew that you would more than likely investigate it. wouldn't have been used as a frost plug replacement as no way of sealing it. Besides one would just drive in another frost plug, wouldn't they

I was talking truck though

pictures of an orig jump seat that I pulled from one of my suburbans a few years back

That's heavier duty than I've seen so far. Do you remember the year and make you removed that from?

There were aftermarket frost plugs that simply slid into place and then you tightened the center screw to compress the rubber washer to seal the opening, similar to the block heaters.

I remember the block heaters and how they mounted as I installed quite a few of them, but they did have a way to seal better than this would

Looks like my '66 gmc has the tracks.
