Hey everyone, I just bought myself an r32 with an rb25 swapped in and going to be replacing the clutch. Supposedly it has an rb25 trans also but truth will be told once I get it out and on the ground. I did notice however that the tailshaft seal (where drive shaft slides into trans) is leaking and was curious if anyone knows the part # or if it will cross with a seal for the z32 trans. I looked around through a few of the sections and haven't had any luck so any help would be greatly appreciated so I don't have to pull the seal and try to have it crossed to another. Also I know I saw somewhere throughout the forum the different numbers on the trans to identify between the rb20/25 trans but can't seem to find it. Is there any other way other than the number to identify it when I get it out and on the ground?

20 transmission is closest to the S13/S14 SR and KA. The 25 is much bigger and the shifter plate is different. On the 25 its on a slope vs Flat for the 20.
