What about parts from other MJs? ;)
I have interior lights from an Army tank,
Extended lower arms from an XJ I parted,
TJ 6" coils,
'YJ brake hoses,
Rough Country adjustable trac-bar,
SOA swapped in XJ rear axle (with a D44 from a '66 IH waiting to go in)
Canopy from an S10 shortbox,
column with shifter from an Auto MJ (and Steering box from an FSJ waiting to go in along with a ZJ brake booster/master)
AW4 auto from a '92 XJ, NV242 too
Wiring harness from a '90 XJ (no more C101 connector!)
33/9.50/15 tires on '96 XJ rims
