but do they mount to the original gearbox/transfer mounts as i dont want to move them if i can help it.
The 5spd is a longer box than the 4 spd, the 5th gear is housed in a "spacer"setup between the transfer and the actual box...... therefore the current box/transfer mounts don t need to be modded. The front face of the 5spd will be 135mm further foward than the 4 spd, this is how you gain the firewall clearance. PM me ya email addy and Ill send a couple of pics.

Correct but you can use your original driveshafts, the transfer will be in the exact same place and use the original mounts.
Mine was an L28 originally so I didnt have to alter anything originally.... but whan I fitted the 5spd I had to make new g/box mounts to allow for the longer g/box, I also had to make new driveshafts too.
The differance in the two nissans ( L28 & SD33 using a 4 spd ) is the diesel motor is much longer then the L28. Nissan simply moved the g/box further back in the diesel to allow room for the motor.

2. What clutch set up is best for this combo?
1.
do not have to move the enginemounts on the L28 conversion
do not have to move g/box mounts on the L28 conversion if using the 4spd.
do not have to move the g/box mounts if a 5 spd is fitted to a SD33.
do have to move the enginemounts if using a 4 spd from a SD33 and massage the firewall too.
do not have to move the enginemounts or g/box mounts if using a 5spd in a SD33
2.
Thats entirely up to you...... I use a
V8 holden flywheel redrilled to suit the chev crank
V8 holden pressure plate.
260mm Nissan clutchplate. ( I'll give out the part number later )

The bigblock has only a couple of problems with clearance and the issues are with the bolt on accessories ...IE: exhaust manifold clearance to steering shaft ( the shaft that runs from the firewall to the steering box). These issues are realitive easy to get past.
