4500/4150 adapter

It's threaded on the dominator side, not on the 4150 side. So to put a 4500 on a 4150 manifold. But I'd bet you could drill out the threads and go the other way...it's 2" tall

I drilled on out to work either way , can use bolts in place of studs.
It is now mostly bolted to a flow bench at times tho------
