Is anyone having problems installing their T/A Differential Cover? I have recieved 2 covers and both of them have been wrong when I attempt to install it, It seems like the top and bottom holes are off by 1/4" to 1/2"? I know I have the right part # so I don't know what to do.

 

Part number should be 1807. No problems with mine.

 

I have part #TA-1807. When I tried to install the cover every bolt went in nice except for the 2 that I mentioned, I just tried to line up my old gm gasket with the cover and it is off aswell which makes sense. I'm going to make a call as soon as T/A performance opens.

 

Has your rear end been swapped?

Here is a pic of mine if it helps. Looks like the holes top and bottom are dead 12 and 6 o'clock.

 

I called T/A Performance and they were really helpful, I bought the cover from a company called White's Pit Stop and they have been sending me the wrong cover. I kept telling them the right part # but from what T/A Performance said they believe I have part #1808 instead of #1807 because the top & bottom hole are not in the same spot. Hopefully I have my problem solved. Thanks for the picture and your help KYSilverado, I appreciate it.
