Hey guys, I am going to be rebuilding my rearend soon, and I was going to just go with a rebuilt f-150 trac lock, but I was thinking, I rarely drive my car on the street, maybe 20 miles a month just crusing to the local hang out if that. I was wondering if I should just put a spool in it instead. Do any of you that have spools in you rearend ever drive them on the street, and how is it. Just wondering. Spools are cheap, and the car is a quarter mile pounder most of the time. Thanks.
