Title: GT 350 auto rear vacuum fitting
Post by: Shawn on April 22, 2025, 08:02:32 AM
Hi - I am looking for any image of the rear intake vacuum fitting for 67 GT350.  Trying to figure out the arrangement for the brake booster and transmission modulator line.

Thanks

Some additional pictures since we have them

Ignore the throttle spring modification  :)

Where did the modulator line for the transmission end on automatic cars?  Since it's not shown on the intake fitting I assume maybe the carburetor?

Thank you both for the images

JD's first picture shows it getting vacuum at the check valve nipple that is typically capped on a 4 speed GT350.
