I don't think they are interchangeable.
For one thing, the mounting bushes are a different size as I've just found out. Which means the brackets are different at least. Although that's obviously not insurmountable.

The GKN variant is on the earlier cars. Service parts are getting rare now.

Readman racing told me the GKN1s are higher geared meaning lower revs at higher speed.

Thanks lads, someone mentioned to me I possibly had a 345? Does that sound correct, can't remember if that's exactly what was said to me, 2000 car, seems quite high!

a BTR is easily fitted to an early chassis, but you need to make the appropriate front and rear mounts. I couldn't find any when i fitted mine, so made mine up.

driveshafts fit fine

Bush sizes are the same, its the bracketry that is different... We run a gkn iirc in the racer as it is far easier to get gear ratio's for it so john reid said. We used one side grackwt as is and made the other side fit so the diff is still in line. As said driveshafts etc all fit fine
