ok, i know for the 80e swap for an 02 silverado 1/2 ton that you can modify the crossmember instead of buyin a custom one from speed engineering. but instead of paying 400 bucks to buy a custom front driveline from speed engineerings page here:http://speed-eng.com/store/index.php?cPath=23_78_1995_1996_1997 can i modify this too?!? like does it need to shorten or what. if so how much does it need to be shortened? also i know gm flexplates are like 100 bucks is there really a need for a SPE flexplate? or will the 5.3 flexplate work with the 80e? also with everything needed to swap an 80e into my truck would be the same with a 5.3 as it would a 6.0 right? im asking this because my 60e is going and it slipps pretty bad so i plan on putting the 80e in then a little bit down the road do the 6.0 swap...thanks guys let me know:shake:.
