It's better to ask questions first instead of taking the chance that you'll ruin something later. There are no stupid(dumb) questions, but you will get some stupid (dumb) answers. Don't sweat it. You're doin fine.
I had trouble getting the yoke out of a 60 chey pick-up one and it tunred out to be a twisted tail shaft in the tranny. I had to use a cable come-along to get the drive shaft out. Then put a new tail shaft in the tranny. wierd stuf happens.
