Gears & Axles - 10 bolt mint whats it worth + questions

i have a stock ten bolt with new bearings and 4.10 in absolute mint condition. and just as quiet as stock....no whine what so ever...how much is it worth???

i plan on a ford 8.8 with 4 link....i think im going to just wing it and fab the shit. but im confused about the brakes....do i use ford? and will my stocker ws6 rims fit?

i wanna have it torn out with in the next month, im taking my car out of storage early just so i have it ready for early summer....

+ i want to do a bad ass wheelie...i really wanna spray a 75 off the line:devil:

btw the gears have only 3-4k on them. and all motive and like i said NO WINE...and feels good...installed by scramblerman on tech, took 8 hrs but was done the right way...
