I'm installing buckets in my 69' el and would like to know do i need to buy adapters for the inside bolts or just drill holes and thru bolt it.thanx:beers:

Barry,

I'm assuming the '69 is like our '72 so I think you will need a set of conversion brackets to get the right mounting points. I hope to be welding ours in this weekend. I've seen two different types.

There is a good thread over in the Interiors forum you should take a look at. http://www.chevelles.com/forums/showthread.php?t=192782

I used the bottom set, what I did was just measure 1" from the outside hole and drilled a hole there, used some grade 8 bolts with wide washers under it. I welded in the inside rails, I think I stuck a few washers under the seat front outside seat leg to level it. When you throw the carpet over it, you cant see the outside mount anyway. jim

The after-market brackets raised the bucket seats too much for me so I just drilled holes through the floor in the correct locations and used large metal squares under the floor pan to help strengthen the mounting when I bolted them in. You get more headroom this way.
