I don't know what else to say. It's the big bolt that the A/C unit pivots on which is also the main bolt attaching it to the engine. I have an 86 1.6 diesel but it's probably the same on any MK2 or anything with a similar A/C pump I'm guessing. The bolt is about 10" long I believe.. I was driving across the country and it fell out at some point. Belts won't stay tight and A/C is rattling all over the place, it's terrible and simple but hard to locate. I'm located in washington state.
I also need a rear windshield wiper dash switch
car is 86 golf diesel
thanks
aren't all the bolts on the AC brackets just standard fasteners? you can find the sizes on the etka or vagcat.com.
