are you sure they make that tall of a gear for a 12 bolt? i can get the 5.38's for the front for like 160. and the instal kits are like 70 bucks a peice. it looks like i can get them in a 5:38 in like a richmond gear but they are like 200 bucks. i think i might be able to get a different cross pin to run the higher gears in the stock carrier if you want to weld them up. let me know if you want me to look further into that. also don't you have to get a c clip eleminator to run a full spool in a 12 bolt? i need to do some checking around for you i think. the 12 bolt seems like it might complicate things alittle. you want me to see what i can find out?
