Where to buy new 1-2 spacer plate & inner servo piston?

[PaulRV6]

I'm looking for a new stock GN inner servo piston (mine is worn), a new 1-2 accumulator spacer plate and the 2 large spacer plate gaskets. Who sells these parts? Thanks

The 'Inner' is the small Steel 3-2 Piston, seal is sometimes left off with Shift Kit. Wear isn't that important.
The 'Outer' is the large Alum. 2nd Piston.
2nd Piston Part # 8678941 $100 here > http://collectorsautosupply.com/search/search.asp you can get a Billet Servo for that.
CK Performance, Extreme Automatics. Local Parts House etc.. should have the other parts.

Ok, but I am still looking for a new spacer plate (the small one for the 1-2 accumulator). Do you have a p/n for that? Thanks

Don't know the GM # but, Aftermarket carries them.
Click on #746 here >> https://www.wittrans.com/Schematic.aspx?Transmission=200-4R&Schematic=4
#320 & 321 are the upper & lower VB Seperator Plate gaskets. Local trans supply shop may have all 3.
