EdwardK Posted May 2, 2013 Report Share Posted May 2, 2013 I have a five speed I'm going to swap into my '74 620. I read through some of the posts where people have done this and I just have one question. Do I need to upgrade my rear-end before I perform this swap? If not, I'm all set. Thanks guys! -EKA Quote Link to comment
darrel Posted May 2, 2013 Report Share Posted May 2, 2013 no. just make sure you use the spdo cog for the correct rearend gearing. either by keeping the carrier from the 4 spd put into the 5 spd. Unless it's a late 5 spd. then swap out the cogs from one spdo carrier to the other. Quote Link to comment
Jayden71 Posted May 2, 2013 Report Share Posted May 2, 2013 Why would you need to upgrade the rearend?? You're not doing a V8 swap or anything Quote Link to comment

Maybe the cog in the five speed will be closer to what I actually need. lol Why would you need to upgrade the rearend?? You're not doing a V8 swap or anything I don't know, that's why I asked. I didn't figure I would need to, but better safe than sorry right? Quote Link to comment
