I have a selection of AE86 engine mounts and two of them are TRD ones.
The problem?
All of the mounts are mixed up!
Anyone know how to tell the TRD mounts from standard?

Assuming they're stiffer, higher durometer, I'd mount'm, engine/vise/frame and then twist/move/whatever the other end with an adjustable wrench or drift punch in a hole and just go by their feel.

Sounds like a plan.
Slightly odd with TRD stuff, l also have some TRD top mounts and there is nothing to distinguish them from standard other than the packaging.
The engine mounts are definitely stiffer, l'll try what you suggest and if l find out anything regarding identifying them from part numbers, l'll post here.
Thank you
