So I have purchased a couple of 3 rib 3.42 rears.
I ended up selling the other ones because someone blew a rear each time and was in need...or maybe I just was too lazy to get it installed before that happened each time.
This time I picked up a 52k 3 rib 3.42 and now I want to install it. It is from a 2003 but it is not the 3.42SP. I don't race so I don't think that it is that necessary to have the Shot Peened gears (The added expense is too much for me right now anyway). It came with a couple of pieces that I imagine are already on my 52k C5 but I would like to know what they are. It appears that one of them is a mount (3rd picture at the top looks like a wheel and 4th picture at the bottom looks like a mount).
I am trying to prepare this for the daunting task (the lowering of the transmission is scaring the poop out of me as I don't want to lower it too much and have the engine hit the firewall) of installing this beast. This is a jackstand job as I don't have a lift. The 3.42 came out of a manual and my car is an automatic so I need to remove the seal plate from my 2.73 and install it on the 3.42. Before it goes in, can I get some input on what I should do to it prior to installing it (i.e. seals, gaskets, fill material, etc...)
