Hey everyone. Is the power brake booster the same for JA1 and JA2 brakes? Rock Auto doesn't list them with a brake RPO code. The master cylinders are listed as JA1 and JA2 and even JA8 codes. I have an 87 Ciera 2.8MPFI with JA2 brakes. Thanks.

I swapped my JA1 celebrity to JA2 with no need to swap the booster.
Nice. Thanks for the info
