I purchased a (rebuilt)12 bolt w/ Eaton posi, Moser axles, Richmond 3.73 gears from ET Automotive in Garland, TX a few weeks ago (very nice work)for my 69. I was getting all parts ordered for the swap and brakes to be redone. I finally got my parts in and the old rear end out. i was doing some measuring and the new 12 bolt was about 2 inches wider than the 10 bolt AND measuring the perchs, i found the width was 3 inches wider than the leafs. I know this is not right. I took all the numbers off the axle and searched the web....found it was a 1970 12 bolt....i believe it was for a Camaro, or maybe not, but i found the info on f-body.com. i called ET Automotive but the main guy was not there and am waiting a call back (he is never there).
What can be done with this rear-end? Do the perches have to be cut off and moved? Different 12 bolt totally? It is wider, but will the 2 inches matter? I think if the perches lined up it would be okay. I spent $1400 for this thing and it was supposed to be for a 69 Camaro (so i was told). I am not a welder, and if anything is done to it it should be done by ET Automotive...they sold me a direct bolt in for my 69. Without knowing what the guy will say when he calls me (if he calls me)...Hope i didn't just get screwed!!
