Yes there is but you wont like the answer. cut off inner C's weld on cj7 C's, you can then run either dana 30/44 outers, jeep, ford, or chevy. problem is bolt pattern changes to 5 on 5.5. the up side is this only cost about $300 and it's stronger. as far as I know there are no lockable hubs with 4.5 spacing. I thought of doing this but for the amount of work i'll chop a hp44 to yj width.
