Rebuilding engine in my 66 GTO using Fel Pro gasket set 2601025. It contains two different intake gaskets(see photos attached) . Which is correct A or B? A is stamped 90205 and R3. B is stamped 9980 and R 4. Also, does the printed side of gasket face the head or the intake or does it even matter?

In October of '09 I bought an aluminum radiator from Performance Years Model RPE40L. Does anyone know ofor can you recommend an electric fan that will attach to that unit with a minimum of aggravation.? I'd like a dual fan unit pulling about 3000CFM or better.

The drivers side fender was crunched and when I bought the car, it came with a couple of fenders.
I’ve started doing the prep work in order to paint but am having a hard time getting a paint match.
I’ve been to a couple of automotive paint stores and the toners are discontinued and the metal flake is too pronounced. I’ve brought in the wiper cowl and they shot the piece with their expensive color match gun.
Still did not match. Way too red and sparkly.

TCP Global has a Restoration shop division that has a code and they claim to have the original super fine metal flake that went into this paint code.

I do not want to paint the whole car, I simply want to paint the fender I’m replacing and have it be as close as possible.

Has anyone ordered paint from TCP and the color be accurate? Anyone have a modern paint code for Burgundy poly? ]]> Tunajoe https://forums.maxperformanceinc.com/forums/showthread.php?t=886017 67 GTO Vacuum Modulator Line routing? clip, need photos https://forums.maxperformanceinc.com/forums/showthread.php?t=885981&goto=newpost Tue, 23 Jun 2026 12:05:52 GMT I'm installing a proper vacuum modulator line on my 67 GTO Auto w/ AC. Previously someone just used rubber vacuum hose. It is confusing how the new pre-bent line is mounted and routed down the intake and back of engine down to the modulator valve on the transmission. Which side of coil does it go past? Driver's or Passenger's side of coil? Is there a bracket, bolt,? where does it attach? How does it weave in between the transmission oil cooling lines? Photos would really be appreciated showing routing and mounting.
