ok so my car is in the shop getting gears put in. What i thought were 4:10's, turns out they are 4:88's. The guy i bought them off put them in a 4:10's box and said they were brand new. Well they were brand new just not 4:10's. My machanic didn't even check untill he was about to put the gears in. Should i keep the 4:88's??? Or go buy new 4:10's and have him redo everything. I really dont have the cash right now to buy new gears.
