My cheaper/simpler tranny mount
 

So I installed the KartBoy shift bushing, Whiteline bushing insert and Mtec shift springs. While installing the bushing insert, I noticed the slop in the center carrier bolt that goes through the bushing.
I've seen some solutions on the market for this, but I decided to fix it myself.

It's just a simple tube I machined out of some aluminum round stock I had at the shop.
I will say.. these simple mods have drastically improved shifting and the over all "feel". So much so, that I had a short shifter but decided not to install it and sent it back. The $200+ will be better spent elsewhere.

What are the dimensions of this piece? (ID, OD, length) I'm thinking there might be an off-the-shelf bushing at McMaster-Carr that would work, depending on the size.

I can't remember the length, but it's 20mm ID, 28mm OD

Looks like there are four possible options, the most expensive of which is still under $5

SAE841 material
6658K47 (16mm long, might be too short, $2.84)
6658K48 (20mm long, $2.88)

Alloy 932
7811K47 (16mm long, again, might be too short, $4.67)
7811K48 (20mm long, $4.74)

Personally, I'd just grab a 7811K48 and give it a shot. The alloy 932 seems to be the better material, and 20mm long is probably the right length. If it's too long, cut or grind it down a little.

question. Stiffing the transmission does it effect the stress on the engine bay / chassis? I read somewhere that because you are stiffing up one part of the car it creates stress points on other areas. This looks like a nice DIY find.

It might/might not. I'll be replacing the motor mounts soon anyways.

The Perrin one is pretty inexpensive
