I recently replaced the trunk floor and floor support on my 70 Satellite conv. The floor was so bad that the support was gone. I noticed that the supports are different between 69 an 70. The 69 version has two sloped pieces welded to them, probably for centering the gas tank. 70 doesn't have them. there appears to be two nuts welded to them that something bolts to, but I don't know what. The repos are the 69 style and that is what I installed. Should I just cut the pieces off ?
