Default Any reason to replace the tranny mount?

I've got my transmission out for a rebuild and I'm putting it back in this weekend with a new crossmember to relocate the TA off the trans. Already have an adjustable torque arm and all new drivetrain parts on there, along with my 12-bolt (4.10s) and rear suspension parts. I just realized the only thing I haven't replaced yet related to the trans/drivetrain is the stock tranny mount. Any reason I should replace this with, say, the one in the link below (or another) before putting it back together? I would have to get the part shipped 2-day for extra $$$.

I have a Prothane tranny mount because I have Spohn solids and I read that you should have a stiffer trans mount along with the stiffer motor mounts. Either way, it was so cheap and easy to install I got it anyway.

I've been told NOT to put in a harder tranny mount without doing the same to the motor mounts. Can't remember why, something about the movement between the motor and trans.

love my prothane mount and would recommened it to others. My shifter is always in the same spot never wobbles or wonders. Best $30 I spent on a single mod Plus the rubber ones break all the time, then the shifter hops up and down like a pogp stick.

Huh, I never experienced the moving shifting everyone is talking about but I went ahead and ordered the new mount anyways. I want to do motor mounts at some point, as well, but don't have the time or money right now.

Well moving meaning it deflects from the movment of the rubber mount. The prothane mount there is no movement what so ever. It stays put. You will like.
