I'm going to start my swap soon & I was wondering:
Can I use the same brackets for the new parts I buy (Alternator bracket, Radiator bracket, A/C bracket ECT)
or do I need the Brackets from the Integra ?

 

for alternator, use the bseries integra bracket, unless you are trying to bolt on a single cam alternator. I'm not sure if the bolt pattern is different.

for the radiator, just use the stock civic brackets.

and the A/C i believe requires a custom bracket to clear everything, I'm pretty sure stock brackets dont work.
