I used them on a 57 chevy car. Had to cut brackets to fit and weld in. fit very well.

I can’t say much about using them in a car but we bought these to mount a basketball hoop to a shed which worked amazing for.

I have 1976 chevy with a small block. I bought these hoping I would have more options in centering the engine. But these are monstrously long. In order to have enough room to use them would require me to cut the original frame motor mounts off. This would eliminate the possibility of going back if I couldn’t make these work. I haven’t given up on them because I feel they would be an improvement over the original motor mount design. I may do some measurements and then pull the engine out for the cutting and welding. But as of right now I’m not seeing any way to make them work.
