ok i am a little depressed right now about the rear end of my chevelle. i really wanted to get it done before winter hits because the only way i can get the rear in and out from under my car i have to keep the garage door open. So as you know i check on my rear and i confirmed that it is a spool with 4.11 gears and strange axles with 33 splines. So i said ok now that i know they are 33 spline let me look at some posi units for my chevelle. i almost cried! they are around $600 bucks! i only have about 250 saved up right now and i was hoping to save another 250 or so get everything i need for the rear. as of right now i am just thinking about leaving it as a spool and just drive it that way! i have so many other things i want to get and do to my chevelle before spring 2012 so i can have the car ready for the road! i am clueless and a little depressed on what to do! sorry had to rant!
