..a few in the nation????THAT WOULD SCARE ANYONE TO RUN AND PAY THEIR PRICES..... i always like to undertake as much as possible to try and make sure its done right and to save some money[fireman's pay in the big apple only goes so far]... i liked the video, it allows you to follow along and see what a shop manual can never do....if it gets confusing just hit the rewind button and take another look ...transmissions,especially an overdrive have alot of parts and it helped me keep it all in order..i had built one other trans prior to this[t350]....i used a core from a Caddy because it was cheap, low milage and not likely abused by a racer.. Its not set up with the GN/SS valve body but i upgraded with a cheap kit and it worked excellent...I was able to make all the tools needed for disassembly and such.....the most needed tool is a dial guage indicator and stand[cheap and easy to find] to set up the clearances[very important from what i had researched]....look in your yellow pages/internet under transmission part dealers and most will sell you the quality kits for cheap as compared to Summitt/Jegs....i enjoyed it for two years of use and ended up selling the car after 9/11....give it a go.
