Yes, Transtar is near 35th ave and Mcdowell.
I'll copy down your suggestions and see what I can find.
Where is a good place for the cores? Junk yards? I'll check the paper too. Do I need to stay with the 700 or can I use the later model 4L60/or E tranny?
I called my buddy in Black Canyon city with all the goodies, but nothing that new. He's into the old stuff.
