    Here is the plan. I have a 1977 K5 Blazer and a 1988 K5 Blazer that will be scapped. The TH350 in the 77 is bust. I want to put the TH700R4 of the 1988 in along with axels and driveshafts.
    Now I heard the 88's computer controlls the lockup convertor. True?
    I saw on that I need some extra stuff. Now they don't respond to my email. But do I need the internal wire kit and the spring kit?

    Thanks in advance.
