For your next learning experiment, here's a link to the section from the shop manual that sez what to do.
http://chevy.oldcarmanualproject.com/shop/1948_51truck/51ctsm1229.htmAfter you have the dizzy back in, and know which wire will go to #1, you just wire the rest of the plug wires, according to the firing order, 153624. We we learned on the site a few weeks ago (thanks fried-green!), you can remember this as too-young, too-old, just right. Hahaha. You might find reading the whole electrical section enlightening. I know I never knew anything (still don't) about car-electrics, until I was forced to, I also pulled the dizzy from a truck once, never dreaming I should have known what I was doing!
