Pumpkin changed, A31 B body would have had a 489 case, A31 includes SUREGRIP so no it is not possible to have one unless the factory installed the wrong chuck in the housing.

What is the date stamped on the ring gear , an A100 I think could be had with a 3.91 with no sure grip and a 741 case.


I have a 3.91 SG 741 in my stash that I took out of an A100 van.
