In the last few months I've built a new M23 Auto Gear transmission with the 2.99 first gear
http://www.hotrodders.com/forum/auto...ld-468129.html and got a new McLeod dual disc clutch. I also built 2 new chunks for the rear end. The one on the left is the street set up with a small bearing nodular case, Daytona pinion housing, 1350 yoke, Detroit Locker and 3.70 gears. The one on the right is a the race set up with a big bearing nodular case, Daytona pinion housing, 1350 yoke, spool and 4.86 gears. I also had a new 4130 drive shaft built by Strange Engineering with 1350 u joints and a 4130 yoke.
