why the front?
Why tj style control arms?
Everyone with a Tj is wishing for long arms at the least.
Bolt/weld on kits won't work for using tj links on a cj frame, as they have different frame widths.A tj axle in a cj would make things worse.

I build custom long arm rear coil set ups at work, with a rear coil set up, all that is major to move is the fuel tank. This allows for a CJ7/yj to be stretched to 100" wheel base. With front coils, on a CJ, narrow axles (stock) are a disaster, no room, less stability, fabbing track bar and steering... On my own tube buggy (in process) I'm running front leafs, rear coils. Cj frames are not much to brag about, so adding anything that stresses an already POS frame could be no fun at all.
