nirtostangracing on corral has good prices on trannys and clutches. maybe you oughta look at his prices, is honest guy and has all good feedback on the corral
I've found tremec 3550's for about $1500 w bell housing, Tremec 500/600 for around $1559. Most say I should change the clutch and flywheel. So to change a tranny is a $2000 - $2500 job? sheesh!
