bought one already...21tooth from cjponyparts (should be red)...and i think they sent me the wrong one..its white 23tooth..speedo is still off by about 10mph...plus the bolt broke off in the housing so now i have to have the crossmember dropped to lower the rear so i can get a drill in there to drill it out and re-tap it...PB blastered it and let it soak to...still wouldn't budge here is what the car has for mods and i will be changing tires in a few weeks i will post the new sizes will it work for both tire sizes?
