I am doing an Olds 260 to Buick 350 engine swap in a 1975 Skylark SR. It appears that Olds and Buick had different frame engine mounts so I am in need of the frame engine mounts for a Buick 350. I am not sure on years (I am pretty sure that 74 and 75 will work but do not know outside of that). The skylark SR was an X-Body so hopefully that helps. Let me know if anyone around here has them!
