Third gen part number

[Z Ya Later]

I'm looking to do the vacuum brake conversion on my GN and am looking for the part # for the vacuum manifold that sits atop the throttle body on the 89 Turbo Trans Am (and possibly other models as well). Would anyone know 1) if it is used on other models as well and 2) what is the part number? Thanks everyone.

If you can't find the part, I believe Poston's sells a billet vacuum block with the brake port.

ATR does too, but they are backordered since Nov. . However, I didn't know Poston's sells one too. I'll have to check them out. Thanks Joe...don't know what I'd do without ya
