Recommendations on a spacer to install a thermo quad on a 1972 340 intake

[Plymouth71]

I am looking to install a late '70s Carter Thermo quad onto a 1972 340 intake to be placed on my 318. What are your recommendations for a spacer, the linkages seem to be catching on the intake. Looking on eBay there are a lot of different options, but I don't know if I can trust the materials.

Phenolic spacers are good

I used one from Summit. Wooden one, never had any heat soak problems.

The original phenolic spacer comes with the carb rebuild kit sold by Mike's Carburetor Parts.

I believe FelPro sells a thick gasket. I just did a TQ rebuild for one of our members, using a Standard kit and it came with a thick gasket and two thin gaskets to use with the OEM phenolic spacer. FYI.

As 493 Mike said, it needs the correct thick gasket. Felpro makes a nice one.

If that lug on the intake, below the carb, is not going to be used, it could be ground/cut off for carb clearance.

I thought 71 and later 340's used a thermoquad from the factory? I am building a 1971 340 for a customer in my shop right now and he has what he says is the correct manifold for his Cuda and it is a thermoquad. I bought a thermoquad off Ebay number 9055S which is a 1971 with a manual transmission carb, to use on the build.

My understanding is, that there may be differences with later Thermo quads. It might also be this one is off a big block.
