I have done the searches but still want some advice before I spend some money. I am going with the T5 transmission. I found a Blazer 4x4 with a T5. Will this transmission work or is it a different tailshaft? NEXT question he isn't sure of the year of the truck, but it is fuel injected so I'm thinking 88, which makes it electronic speedometer, what are the options with this if I want to keep my original gauge? LAst, this Blazer differential I think would be perfect for replacing the original differential. THANKS for any help!
