Accesories with Headers

For anyone that has headers installed, how do you accommodate the accessories that mounted to the OE manifold studs? I have a 91 Z28 with AC and AIR pump. The AC may have a bracket, but I know for sure the altenator has a braket on it's backside that mounted to the front driverside manifold stud, and the Engine oil dipstick also mounted to a manifold stud on the passenger side. For my headers, I had to use smaller head bolts. Are there kits to remount this stuff, or was fabrication required?

Thanks,

Re: Accesories with Headers

Did you fasten the alt. bracket and dipstick to something else?

I used the stock longer studs in those holes and bolted the brackets back onto them.

Spacers, perhaps. Maybe the following pics will help, maybe not:

Re: Accesories with Headers

My bad, I guess I forgot to include the two spacers.
Get some tubing from the hardware store, 3/8" inside diam. 1 1/4" long and reuse the stock bolts on #1 bolt left side and #3 bolt right side.

Sorry 'bout that.
