3 questions
#1. Those of you that have Z'd your frames and made your cuts at an angle to center the front wheels, how did you come up with the degree of angle needed? Does it vary depending on the amount of the Z? Will it vary between doing it to say a 67-72 and a 73-87?
I know i'll have to move the mounts for the radiator support back along with bumper mounting holes. #2. 73-87 2wd 454 coil springs, how much difference is there between the 1/2 and 3/4 springs? #3. Can you/has anyone used a 2" drop hanger but not use a drop shackle with it?

Re: 3 questions
This could cause pinion angle issues. Is there a reason why you would do one with out the other?

Re: 3 questions
when you z the frame at an angle what do you do with the core support. do you have to z it in the opposite direction to pull everything back so the fenders line up. i always wondered how you pull everything back once you pushed it foward.

Re: 3 questions
Why not just cut it straight and not have to worry about it

Re: 3 questions
Are you referring to the frame/suspension Z or the required core support mod?
Cutting the Z @ an angle allows moving the spindle center-line forward to keep the wheels centered in the wheelwell opening. If it's the core support, there's no need to move it @ an angle. It could be cut straight w/the appropriate amount of material removed to keep the dimensions similar.

Re: 3 questions
gotcha, so you just remove the material and move it back. i see. it is kinda funny to me when people z frames and the way they look without the sheet metal. it seems like it works, bunch of them out and about.

Re: 3 questions
Agreed.... although some appear much better than others simply due to the planning & skill level of the fabricator.
