I need advice on LC Prime and LC Ironhide alterations.

OK, I tried to check out the kitbash/customs forums to post this, but I couldn't really find a right place, so here it is.
I have both RoTF Leader Prime and HftD Battle Hooks Prime as well as DotM Leader Ironhide. All 3 of these are in robot mode and will stay that way. (I've been actually thinking about selling the Primes, but I doubt I'd get good prices for them.)
Anyway, what I need help with on all 3 of them is removing the arm panels. Is there an easy way to do this? To remove the pins in the hinges? Also, I want to remove the rear tires from Ironhide's legs.
Any suggestions from those of you well-practiced in alterations and mods?
