Is it possible it's for a Military vehicle....?.....
also How much did it run Ya..?
it could be. IIRC, 181s were used as military vehicles in here and also Thailand. Back home where I am from which is about 2 hours flight away, we have probably less than 10 181s in the whole country.
i paid approx USD30 for it. i have always wanted a mint unit like Glenn's, but most cars here have the heater snorkles cut and welded shut, and cars those days were treated rough, so i am still looking.
if i get a mint unit, i will cut this open just to see the inside...LOL
