I was going to suggest a simple LUK replacement. They are stout and very easy to drive. Sounds like a fun truck I need to get my super charged 5 speed rcsb back in action soon I miss the torque.

It's a work in progress and taken some time to get it driving.

I'll feel better about it once there is fresh gas and a tune.

I was just planning on a Luk clutch setup from summit, flywheel and hyd slave. The current setup was a nightmare to get old fluid/air out of it, and sometimes makes a loud scratching noise when slipping the clutch to get started.

well, pretty much anything's bigger than those tiny 29"s, so if the last calibration was with bigger tires & a 3.73 rear, i could see it making that much difference.
and i second the clutch decision. my last 2 or three were LuKs & held fine.
