Moving seat mounts back

[MMorgan62]

I am looking for information on properly moving seat mounts back . Have heard there may be an adapter that would bolt on to the existing track? Any ideas or experiences would be welcomed. Thanks.. I should mention I have bucket seats and only need to move drivers side.

I think you'll find it'd be pretty easy to make them yourself just by looking at the pics.

Perfect, thanks for the link. I have the flat stock to make those . I guess the only down side is it probably takes the thickness in headroom away. That’s a bit of an issue as well. Ha , will have to take my hat off!.

I like the one piece ones you show, Cat.. and available! Thank you for the link

Even if you use 1/4" stock, shouldn't make that much of a difference, but if you're 6'+ every bit counts.

Have been checking out the options on different adaptors available. It looks like the 1 piece ones have fitting issues, the four piece has good reviews . I think I will make a set like the four piece set. Thanks for all input.

3/16" stock should be more than adequate. Show us your brackets when you're done making them. Even better, document it in the Chevelle area.

Your seatbelts are your primary restraint, the seats are a factor, but not designed to hold you in place. I'd think if you're moving it back 2 inches, 3/16 would be enough thread to secure your bolts. So, you're only raising the seat that amount.

Here are instructions on how to accomplish this without buying a kit :

Increase Bucket Seat Legroom Tip 1966

From 64Tempestwagon @ Team Chevelle

First detach the two tracks from the seat. Remove the side covers as well. The rear portion of the seat frame in front of the rear preexisting
holes dives down about a 1/3 inch. I put the track onto the seat frame there and drilled a hole in the seat frame there (feel the metal there it's 2 layers thick).
I used a grade 8 bolt, lock washer, and nut there. It moved the seat frame forward about 2 inches.

Then I saw where the front of the seat track needed holes in the front over the preexisting two nuts in the front of the lower seat frame.
I drilled a hole there and used the same bolt there to fasten the seat to the frame. The seat tracks then stuck out 1/2 inch and I cut them
off so the seat side covers fit.

That kit is way over-priced considering it only fits one side and can easily be copied by someone with a little time
and hand skills. The square slots are easy to make by drilling two holes and using a sawzall or jigsaw to connect the dots.
That's if the slots are even nessasary at all

Went to town bought some 3/16x 2” stock . Got them cut,drilled out, and painted . I drilled only 1 set of holes instead of 2 like the ones for sale online, but gave myself 2 1/4” of leg room instead of 2. I am going to install under carpet . With that said , I could have ordered a set of pre made for around 33.00 shipped . I paid 30.00 for a 3’ piece of stock. Pro’s , it took me 30 minutes to make they are here and done instead of waiting a week . 64Tempestwagon, looks like you have a good method as well without loosing any head room. I will see how this goes, if it’s an issue I may go your route. Thanks all for the info. I’ll follow up with some install pics .

And you have 2 feet of spare flat bar, win win.

Day two, after fitting brackets , I decided to put bends in rear brackets to gain a bit more head room. Also welded bolts from underside for easier install,Then pre fitted . Brackets are now under the carpet, with just the bolts sticking up through carpet. Reinstalled seat. Turned out better than anticipated. I gained 2 1/4” of leg room, and about 3/4” much needed head room. Can’t tell there was a modification.

Nicely done. Excellent job, and now you ride a whole lot more comfortable I bet.
