engine and transmission swaps are where they really shine
should i get these if i have a 91 ho motor and im gonna do a T5 conversion
Did you not read the previous posts?
Only if you really want to take the easy way to get everything to line up perfectly, should you get the RMP mounts.
If you prefer to struggle, sweat, blead, cry, scream, throw tantrums, get frustrated, get behind, chase bugs, give up, then don't get these mounts.
The biggest problem that I can see with the RMP mounts is, they work so well, that dropping in the drivetrain becomes a non-event.
What kind of bragging rights can you have when you don't even get grease under your fingernails.
Because they use polyurethane isolators, they will transmit more vibration to the chassis of the car. Most people aren't clued in enough to know the difference.
Eventually the bushings break down at the bottom (higher exhaust temps speed the process). So "eventually" you may need to change the bushings.
And if you really want to get things "just right" get both sets of side plates. If possible use the lowering plates (especially with a transmission swap).
If you are bound and determined to do things the old fashioned hard way. And you grew up walking barefoot in the snow 4 miles to school (uphill both ways), then by all means, check out the below link:

In either case, have fun, and good luck.
