poly motor mounts different sizes

[Guardians91240SX]

Hey guys so I am finally back in the 240 game with a '95 zenki, my question is when i pulled a full 5spd swap with harness it has poly mounts, unsure of the brand, possible isis/isr, but they are different heights, I just need to know which side goes where, and yes i do have the 1/4" thick aluminium spacers that go with it

Thanks,
-Mike

Looks like ISR or Circuit Sports. All mounts I've dealt with have been equal in size iirc. Check the diameter to see if one is deformed maybe? Like the shorter one is fatter from being squished. You could call ISR or C.S. customer support and ask them. I did read that nismo mounts for KA are equal, but for CA are different in height, by about 10mm. Perhaps someone else knows for sure.
