ok so here the question how far should a slip yoke hanging out of the tail shaft i thought 3/4 to 1 in am i right ? here's a pic i stole from the Internet i know the measurement is wrong on it just using it as reference so you know what im talking about here's the problem i just did a engine swap in my truck went from a 350 with a 4 speed to a 383 with a th350 i know i know why swap the auto the wife is gonna drive the truck and that what she wanted . so anyways i was planning on haveing the drive line remade but when i put it up every thing seemed to fit perfect . the truck is bagged so i put the drive line in the the car slammed on jack stands and it went in perfect down and up brings it out farther . id say there a 3/4 in play when the truck is down . here's the problem why im asking there seemed to be a binding noise under the car i was thinking it was suspension but being it started after the swap it cant really be so i was moving the truck yesterday and in the all up position the noise went away so im thinking maybe its the slip yoke in too far . if its in to far what damage will it do to the trans . of course im not gonna drive it like this id just like to know if i could damaged anything . gonna re measure everything and recheck but just would like to have some insight first as im not a trans guy . thanks for any info kyle..
