i can tell u it is a pita, the rear mani is the worst, i was planning on doing mine but hit a snag and ran out of time so i ended up dropping it off with a friend to finish it, he said he had to drop the engine out and it supposedly took him about ten hours on a lift, which i think is bull but anyway..
i would advise headers over a dp plog combo just in case you wanna take it past a 3.4 setup
