riddle me this...

[Rosey1968]

So I went to put my shiny new TA rearend Cover on '87 GN and it does not fit... 3 of the bolt holes are off just about 1/8". See attached pic.

I pretty sure I ordered the right cover... TA1807... the cover say 'TA807' on the inside.

I think the rearend is original to the car... the codes on the tube are 3TP G 131... that is a 3.42 right? Not sure how to tell if the rearend is original to the car...

Any insight would be appreciated.

Call TA Monday and they will make it right.

They make rear end covers for many brands, so it is possible to be mis-boxed?

I am sure you are correct but what is weird that the model number of the cover says it is the correct cover.

Thanks for the link... I believe it is the original rearend but it has newer Yukon 373 gears with and Eaton Posi
