I have two friends with 93 Civic's with Bseries swaps, and both of them broke there dr. side timing belt mount. One of them broke the bracket too. One of them told me that neither one of them was using the A.C. mount causing this to happen, I guess from hitting bumps or shifting hard. Is this true because I didn't think that mount was all that important in supporting the engine. All I thought it did was support your A.C.
Being that I haven't done a swap yet, I guess I'm kinda learning from there mistakes.

it supports your AC and it stabalizes your AC with the car's frame so it doesnt bounce up and down like it did for you guys. If you want, look at my FOR SALE link above. I am selling a B series AC bracket from a JDM Integra Type R along with the AC Compressor as well. It should definitely fit your engine and setup. If you want to buy both items, I will give you guys a great discount. Hopefully, you guys fix that problem. Good luck!
