8.25 can be found in any A-body 73-76. Some would be obvious like a '73 340 or any 360 car. But for no rime or reason, they can come in a slant car also. Your drive shaft will need to be shortened. Also, you'll need different shock mounts or drill the ones you have. 8.75 rear ends could be found in A-bodies 72 and older. Just another option would be 8.75 B-body rear end from '65-70 years. Plenty available and usually cheap.
