I have a 71 b50 & am trying to figure out if I have enough oil in the transmission. The dipstick is gone & I have nothing but a plug. How long was the original dipstick from low to high? It's showing up as 40-1033 in my parts manual and I found one for $60 somthing dollars for a plastic part. $60 seems high for a plastic ruler. If I can just measure from the top of the case (top of threads?) to low & high mark I should be good.

hello-if its any help i can tell you how much oil you need in your transmission...5/8 of a pint or 280cc-as far as getting a dip stick maybe you could try klempfs british parts-(507)374-2222 he is located in minnesota but i had good luck getting the proper parts from him....oi dave
