Urethane trans mount mod (the "Kelly procedure")
#16
Thanks for the feedback guys -- George D's pictures were exactly what I was looking for. I haven't decided which way to go, but it's good to know that you can knock out the kelly procedure overnight and that the window weld procedure can be done on a spare mount.
FWIW, I checked out the shore hardness of window weld and it's listed as 55-60A. It comes out of the tube in a tar-like consistency, which is why you can do the Larry Parker / George D procedure to a mount that is not bolted to the cross member. Window weld hardens when exposed to the moisture in the air. The japanese car guys who use it for motor mounts sometimes have trouble with it not fully curing when they pile a ton of it into a motor mount. I would guess this occurs because the stuff in the center never gets exposed to adequate moisture if you really heap it into a big void. No one has ever complained about this on the 944 tranny mounts that I've seen searching through RL, but I would imagine that if you tried the full-on Kelly approach with window weld, you'd have some issues with it not hardening fully.
I'll post up pics and a writeup when I knock this out in a few weeks.

I went Brians route, quick pic but you get the idea. The red plastic film was used to reduce the mess while compacting the goo.
