CJ style mirrors on mine too. If you mount them just right, the RT side can be pulled down and the windshield folded. (A massive plus for me as the windshield is folded all summer.)
I got these narrow head's from a mirror kit my dad bought for his Rubi and did not like them. They fit a spare set of stainless arms I picked up perfectly!
PS: Yes, she is a YJ. And a little CJ....and some TJ... I guess if you count the mirrors, and little Rubi too!
1991 frame and tub, CJ front clip, flares, and tail-gate (soon to be dash) and a 1998 TJ 4cy-FI & 5spd.
