Accessory Studs for Dyno Dons Headers
I have a ‘88 GTA that is getting a new 355 with Dyno Don Headers. The front bolt on each side is used for a support bracket (AC brkt and Power Sterring brkt). What have you guys used to get to the proper location? I was going to buy some stainless spacers but I think 3/4” is too large for the space to the first header pipe. I saw one guy suggested thick wall pipe.

Do you have the studs?
If so email me your address and I will send you some spacers.
I make them from 1/2" tubing with 3/8th inside diameter.

In those 2 locations, use the OEM manifold bolts and the sleeve spacers Don sends you.
