factory bucket seats?
 

where do they bolt in floor thanks scott

Are these 67-68 style or 69-72 style? If 67-68 then the frame will bolt using same holes as bench seat. If 69-72 then you need to drill holes for each seat and the console. What I did with this style is use the front outer hole used by the bench seat as guide for both driver and passenger seats, then drill the remaining holes. Reenforce with washers underneath. I'd test placement the seats before drilling. The remaining holes existing for the bench seat will go unused.
