Hey troops
I am looking for the diameter (using vernier calipers) of the indexing bore on the rear of the 4l80E tranny.
The kid and I decided to go with a 4L80E on the Army truck project to get an OD
Currently the task is to get a "married type" T case of substantial strength to snuggle up to the 4L80.
Problem being, we need a left hand drop on the case and most of the newer LH cases are aluminum and just not all that great strength wise.
Either going with a NP205 OR an NP203 Ford style.
There is a bit of mods to get these two items to get intimate but it's not too tough.
The issue at hand is the slight difference in the indexing bore diameter between a TH400 and the 4L80 as they are reported to be different.
Some info here would be most helpful
Thanks
