I found the rebuild kit and shift improver kit at www.northernautoparts.com but I could not locate the:

Booster Valve Upgrade (transtar part#7028V)
Differenal Safety Pins (Transtar part#72984)

Where can I find the above?

I am going to buy:
1) Rebuild Kit
2) Shift Kit
3) Booster Valve (??)
4) Diff. Pins
5) New solenoid pack (~$100 from ebay??)
6) Input/Output Sensors

Anything else I am forgetting for a complete rebuild (parts)?

Thanks.

PS- Anything to pay particular attention to? I currently have the valve body off as well as the front pump and input drum. Advice would be appreciated!!
