Stock converter?? (pics)





The code is on a sticker when it leaves GM.
You might also find match marks on each half, on the OD, one mark on each side of the weld where it was marked so it could be realigned (and not rebalanced) when put back together.
D=30 spline B29
G=1200-1400 stall speed
H= carbon filled clutch
F=basically means not from a diesel
In addition to what I said in the above post, the yellow marking is a date code.
I had a girlfriend that used to deliver for the biggest converter rebuilder in south florida, and I spent a lot of time in their shop.
