2 rods short of a 3-piece set up.

I just swaped a 4-v 3-piece set up on my 85 truck. used the LD4B intake/square-spred bore open adaptor/q-jet with mopar throttle lever.

had to splice in 2" of round stock to the middle down rod to get the adjustment in the middle of its travel/throw.

I can post a pic of that in the am if you want a looky see.
