I blew the seal in the back of the transmission where the driveshaft slids in anyone know a part number or something that would interchange, I am running a RB25 transmission.

Anything is better than what I have right now

they are the same transmission. Same yoke thats used for the z32's is the same as the r33's Gt-ST. It should work.

I'll add a confirmation if it will make you feel better. I'm running a Z32 slip yoke in my RB25 transmission. They take the same rear transmission seal.

I Dont know if the guy i dealt with at the part store was just a 3rd grade dropout or what I went and picked up the Z32 seal and it was tiny compared to mine, so I had to return it and measure up the old one. The specs I got are42mm I.D, 58mm O.D and 8mm width (or thickness) works fine F illed it up with Redline Shockproof, definitly noticed the differance +1 for Shockproof
