Also made a decision on the transmission, going to use a 4l60e. Found a shop that is recommended by everyone in this area. I'll be dropping it off as soon as I pickup a core.
I wish I had done mine like that. I didn't want to screw up anything though so I kept all the pins I needed in place and just pulled the ones that didn't have anything to do with goin fast! So, my computer sits in the space normally occupied by the vapor canister at an odd angle secured with a couple bungee cords. When I get back at it I'm going to build an air cleaner box that the S-10 puter mount I bought will bolt to the top and have the filter under/inside. For now it seems happy where it is and I'm having too much fun driving it!
