John, I put 2003 (99-2006) Silverado bucket seats in my 52 panel and they sit on top of the seat riser. I think your 49 probably is the same. Most want seats with the built in seats belts.
Buckets in my panel...

Note: I used bolts that went all the way through the seat riser and used BIG washers on the bottom for strength "just in case".

I do know several guys have used the seats for a Buick LaSabre. Depends on what your after. Hope this helps.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
