Converting my 1970 Cutlass from bench to bucket seats using stock 1970 bucket seats. I see there are conversion brackets (https://www.opgi.com/interior-access...n-bmb0001.html) and stock/restoration brackets (https://www.opgi.com/interior-access...t-c240658.html) available.

Which is the better set to use, and why?

 

The conversion brackets (top set in the pic) use the factory bench seat bolt holes front and rear for the outer seat track and the seats may sit a little closer to the door than factory. From the factory, the only bolt used to mount bucket seats was on the outer rear foot in the outer hole. My 72 bucket seat car only has 1 hole in the floor at the rear seat mount location. The other three mounting points were all studs attached to metal braces as seen in the lower set in the photo. Either set would work, but the lower set is correct. I would say it comes down to if you feel the "originality" of the lower set is justified by the higher cost.

 

Here are some pics of my 72 cutlass floor. The photos with tracks are on the driver side.

Thanks! I'm not worried about originality, but I am a fan of correct. Only $15 difference between the two, and I'm in way too deep to worry about a small amount like that lol. I'm lucky to have the donor car on hand as well.

I think the full brackets will be the route I take.

 

You want the 4 piece set (2 longs 2 shorts), which is OEM style.
