Do you have any axle or drive line parts, accually any parts at all for a 1979 brat? Also do you know any interchangable parts from other vehicles? My brat never had air conditioning but I bought some of the parts off line to have it added and now I cant find the rest of them. It has the air condition switch on the inside panel and thats it. I would appriciate and information you can give me. I inherited the brat from my dad and would like to keep it running. Thanks Kathy
