you should fasten the arm that hooks to the pickup coil down in the same spot or you will be messing up your timing of the rotor to fire under the correct pin of the cap. I think if you just leave the advance unhooked and maybe put a tack weld on the rod,you would be just fine.

go to your gm dealership they make a plate that you bolt on and it locks it where you want it i believe they came on c-60 dump trucks

just pull it all out and put one of the screws that held the vac on. back thru the hole that the rod was in, you need to flatten it a little and i snip the end of it open..

you can put it in any position you want, it doesnt matter.

as for hitting the right post on the cap, thats call timing..
