There's a thread showing how to put a later passenger seat into an early car, but I can't find it. It involved welding in a seat adjuster, if I remember correctly. I've searched, no luck, anyone know where it is?

Thanks.

Should be easy. Weld in the same seat mounts that are on the driver side. Restoration design sells them.

plus you will need adjust bracket the mounts on the crossmember. My 70 has a a later passenger seat. I would take some pictures for you, but my car is at Brad Mayeur's shop getting a spring time work done.

I've had a design for a bolt in conversion since 1985.
It will be available as a kit in the next month or so.

Will I be able to afford it, Chris?

I know there was a thread or mention in the thread, even thought I saved the link, now I'll be damned if I can find it.

Thanks, gents.

Any just bolted the seat rails to the floor in the back and through the box-brace in the front. Nothin' fancy.

This is my original product photo, taken in 1986 I think.

Dude! I thought he was German?

The seat-rails fit into the rear (fixed) studs, all i had to do is use some flat nuts so the seat can still move.

Same in the front, there are already threaded holes in the crossbeam that i used to secure the rails there.
No welding or cutting needed.

The only thing you can't do with this method is to tilt the seat up/down.
