It is hard to find, had to go through a link on Classic Olds. Not sure why they stop at the 77 model year. They are same on the Cutlass and big cars till 1990. They are good to deal with bought a few parts off them. Their engine dipsticks fit very tight and don't need the bottom trimmed unlike the chrome replacements.
 
The website that was popping up for me looked nothing like that. Which ones fit my cutlass, the 350 or 400? Isn't the 455 more wide than the sbo?

i believe small block mounts might be shorter....? Check CO for details; I'm sure Joe P. will be quick to set you straight :roll:

As far as a torque limiter, I had a length of chain from an accessory bolt hole on the head to the steering box bolt. Twist the chain to get the slack out.

All 73 to 90 RWD mounts are the same. Don't ask Joe, he got very crusty when I asked that. The 68 to 72 SBO and BBO must match the frame pad they come off. I forgot to switch my 70 motor mounts when I put the 260 in the 70 in my 88. Only half the hole will line up with the later frame mounts.
 
I had bought the mounts already early this morning and then sent an email asking if they would fit. So.etimes i do things *ss backwards 🤣. Pretty sure they will fit since 403 and 307 use the same mounts. Hopefully I get them by this weekend
