'66 Bucket seat track length question

Hello,
Our '66 started life as a bench seat car. 1'st owner converted to unknown, but not Chevelle buckets, by bolting them to the floor. When we were starting the restoration a few years ago, I picked up a set of Chevelle buckets on craigslist. They looked good, until I got the covering and foam out, frame was rusted through.
Thought we could salvage the tracks, and picked up a pair of Dynacorn frames. Probably not our best decision, probably not our worst.
Found the sticky with the proper brackets, which we will have welded in. Today, we tried to mount the tracks to the brackets, and seat, and found the inboard track is shorter than the outboard track on each side. The previous owner of the seats had, it appears, built a bracket for those two tracks, I think? This can't be a factory bracket, can it? If so, why not just make the track the correct length?

Assuming my inboard tracks are wrong, and the adapter, which is roughly 1/4" thick, will push the seat up, any thoughts on the best option to correct this?

Thanks
Greg

Re: '66 Bucket seat track length question

Is one track taller than the other? What is the center to center measurement of the bolt holes where the track mounts to the floor? Sounds to me like you may have NOVA seat tracks. Please post more pictures, with some of a side view. 1966 slides should have the front bolt holes notched out, not completely enclosed like the rear bolt holes would be. I do not think you have 1966 slides for an A body there. Black knobs on the lever did not come out until 1971. A 1966 usually uses a weird shaped chrome knob on the lever.

Re: '66 Bucket seat track length question

That extra bracket is not from GM. Both of the tracks for each seat should be the same over all length. Your do not appear to be the same length.

Thanks, will take some additional pictures. I know they aren't '66 seats, they came with latches to prevent them from moving forward. Thought they should be the same length, and appreciate your confirmation.

Re: '66 Bucket seat track length question

If they have steel back panels and steel lower panels with seat back locking mechanisms they are 1967 seats. The tracks would still be mismatched.

Re: '66 Bucket seat track length question

Good info, thanks. They did have steel backs and bottoms. Would love to find out how they ended up with a mismatched set of seat tracks, they did look like they had been on the seats for decades when I pulled them off.

Re: '66 Bucket seat track length question

Could you post a picture of the slides for your other seat? I think that I may have this figured out, but need more pictures.

Does anyone know where to source these weird shaped chrome knobs? I need both for my '66!

'66 use one a year only steel seat back, because there are no openings in them for a seat back release. (there is no seat back lock on a '66)

Here is a picture of the seat tracks that came on the strato bucket seats that came with on '66. These are not original '66 seats, as they came with center latch releases on the seat backs. (I removed the release mechanisms altogether for my '66) But I do think the tracks are the same as a '66 strato bucket seats. Driver side tracks are at the top of the photo.

Re: '66 Bucket seat track length question

1966 seat tracks have notched front bolt holes. Those have enclosed bolt holes. They are from a newer car than a 1966. All the 1966 seats that I have seen had notched front bolt holes. If those black knobs are original to the slide tracks, they are 71 or 72 slide tracks in your picture.

Then these tracks are probably a match to the strato buckets, as they had the "center of the back" push button lock release..... which I think started in 69?
Yes, they came with the black knobs, but I don't know if they are original knobs or not.

I'd LOVE to find those '66 chrome knobs you spoke of!

Re: '66 Bucket seat track length question

They are kind of hard to find. I do not think I have any extra on those.

Re: '66 Bucket seat track length question

aren't those chrome knobs repopped? I could swear that they are

Yeah, we're runnin' a little bit hot tonight,
I can barely see the road from the heat comin' off,
You know what I'm sayin',
Ahh, you reach down, put it between my legs 'n
ease the seat back,
She's runnin', I'm flyin',
Right behind in the rear view mirror now,
Got the fearin', power steerin',
Pistons poppin', ain't no stoppin' now,
PANAMA!

Re: '66 Bucket seat track length question

are they the same knobs for all GM A-body buckets?

Re: '66 Bucket seat track length question

both sides are the same, the track with the latch is long, and fits to the repo frames we have. both inboard tracks are short, and don't mount. Its weird.
