I'm looking for what appears to be a hard to find anti-stall dashpot for a 1967 Pontiac GTO TH400. The original GM/Delco part number is 7026290 ("Throttle Return Check Assembly") and I've seen some NORS listed as DP102. My 4 bbl Qjet is a 7027262 with a M6 build date (December 1966).

The part I'm seeking appears to have the lever/bracket integrated into the unit - see attached photo. I'm not looking in connection with a high-end restoration, but would like to replace the part along with a carb rebuild. It is an a/c car. The original vacuum lines are still in-place and I have the bracket from the original dashpot, although the diaphragm was cut off at some point in the past. I may re-drill the bracket and install a more readily available dashpot, but thought I would check in here to see if anyone has a lead on a complete replacement part.

Thanks in advance for any help you can provide.
