    What grade are you suspose to run in between the bellhousing and the engine, just standard stock or anything more.

    Also i am going to be running grade 8 fine thread 7/16 bolts for the crossmember is a 1 1/2" long enough or just a inch?

    I replaced my old 700r4 with a new one from B&M and couldn't get the last bolt in so I am running with 4 also! :haha:

    I've been stressing about it. That was the first time I had ever done a big job like that myself and I didn't have anyone to help me out with it.

    Right after I installed it I had a U-joint fall apart on the highway after I smacked it backing up and I thought my entire transmission fell out on the highway when I heard that drive line smacking around under there.

    As another point, make sure they are long enough. Short bolts will work themselves out when a longer bolt won't.

    (this is in regards to bellhousing)

    For the crossmember, you might want to get bolts long enough that you can use two nuts on them, just in case like mine, they want to work themselves loose over time.

    lol yeah, although on the 71 it is all iron though

    id maybe worry a little with just 4 on the 700, but im sure it would be fine, hehe unless you really drive hard or something crazy

    good luck petry
