Good luck with the rebuild. Dont forget to replace the oil pump, I found out there are two different ones to based on the size of the oil mounting bolt. They are NOT interchangeable.
Thanks tbucket! I will PM you about your left overs . I am going to pass it on to my brother so he can tell me what exactly we are going to need first but I'll hit you up.

I definitely have the oil pump on my list since that was the one thing I was worried about before. Thanks for the heads up, I will get the specs off the original to verify.
