Help with Throttle Body ports for Howell Kit

[vanplumley]

Ok guys, as always, I've tried to search everywhere and I'm sure one of you will explain it or link to another post and I'll feel stupid but here goes.

The diagram Howell gave me has three ports on the front of the throttle body labeled J, A, and C.

My problem is that on the front of my throttle body, J is blocked off on the left side (no hole, nothing nada, see pic)



But there is a port on the right side labeled S. After poking around for pictures of TB's on the interwebs, it looks like there used to be two ports for manifold vacuum, Left manifold vaccum, and right manifold vacuum, so I'm assuming that I can just replace port J with port S? Which should go straight to the distributor, right?

Thanks everybody

So really, instead of being like J, A, C like this,



I should just swap the order to C, A, S(instead of J)

Right?
