There's a CJ10 on the Knoxville Craigslist for bout 1200 or 1500, has a fuel delivery prob or something. Looks like it's very soild, been on there before and didn't sell.Factory tach is definately a rare option, but not too hard to find, I have two in my shed.
Some of these are rare, some are just getting damn near hard to locate now.
Levis editions
Actual 1981 anniversary cj's that are also golden eagle jeeps
Warn Overdrives
V8 in a CJ8
J10 tugs
Semi Floating 5 lug D60 rears from J20 trucks <- very hard to find, very desirable, only years were 74-76 I believe
The guy I got mine from said Jeep's are suppose to leak. It keeps the dust down on the trail....another rare and desireable option, a CJ that doesn't stain yer garage floor
(I know, I know, it's just a low tech chassis lubrication option)
