Stop in for a cup of coffee

The kickdown linkage is all wrong. The 360 came out of a c body and it's a completely different setup than an A body. The c version has a lot of room to extend back where an A body doesn't, so the A body version is 3 rod pieces swiveled together instead of a one piece curved rod.

So I need to piece the A body setup

You can use the 318 2 bbl version on the 4 bbl by just lengthening the rod that goes from the throttle bracket to the carb stud by about 1 1/2"... I've done it many times...

You can buy a nut coupler from Grainger and then just use the correct threaded rod...
