Hello!

I've recently replaced my oem AP1 (2001) brake booster/MC with AP2 counterparts. I read somewhere on here that they are identical. Upon putting it back together I noticed the brake line fittings from my AP1 are smaller than the AP2 female ends on the MC.

Does anyone know exactly what sized/flared adapters I need to mate the AP2 MC to the AP1 lines? From playing around it looks like I need an M10x1 Female to M12x1 Male Adapter and I should be all set, but does the flare matter?

Also, Would I be able to use my AP1 MC on an AP2 Vacuum booster? I've found conflicting information on this as well.

Thanks in advance!
