Any advice on re-using the existing mounts? They appear clean and have been blasted and painted.

I recall hearing repops aren't as good?

Mine were toast, so I just replaced them by repops, They were broken in half, the old ones!

I thought the repops fitted really well..

I thought I had read here in the past a bunch of issues with repop mounts.

Anyone?

I heard that Mitty mounts were better because they were US made, then there was a lot of discussion over at PY about how they were actually also made overseas...

I just purchased a pair of Mittys to replace a brand new set of repros. With the repros I had a lot of trouble getting both the engine and transmission mounts to line up correctly and now my oil pan sits barely above the cross member. I have to pull the motor out anyway to repair an oil leak so I am changing motor mounts.

The one thing I noted right away when I received the Mitty mounts is that they are labled left and right.

I didn't like either (repos or Mity Mounts.) The Mity Mounts wont fix an oil pan hitting the frame problem.

To clarify my question, if the original mounts(130k miles) are cleaned up and visually look good, are they OK to re-use, or should I replace them with repops?

They look good, but Wouter's broken one scared me a bit. I don't want to be re-doing these next year...

I have repops on mine, now 2 years old and no drop from the original clearance. The construction of mine looked good....

Mind you, mine were 42 years old, so maybe your old ones are still good!

dont go with solid mounts?

Probably a good way to knock your fillings out. Good for race cars, bad for NVH (noise/vibration/hardness)

Replacement mounts seen to be hit or miss

There where no factory left and right. But some aftermarket makers weld an extra rod on one side(rh) do to the engine wanting to lift and break it.

No solid engine mounts. That can crack the block. Especially on high performance engines.
If you want solid, go with a front and rear plt.
