So I finished my Auto to Manual swap (700r4-SM465), and now that I know that I did everythig right, I have to have my drive shaft lengthend. My old driveshaft was about 29.5" and I'm thinking that the new one should be about 31", but I'm not totally sure how much travel I should have in my slip yoke. I've got between a 4-5" lift and I'd like for the yoke to be almost fully compressed (?), inserted at full compression, so I'm thinking that at normal drive height it should be out about 1.5-2". What do you guys think?
