Looking for more help.are there any pitfalls when removing and re hanging the doors.I want to remove and do body work,painting,etc.

Unless you want the hinges off to paint separately, the easiest way is to unbolt the door from the hinge.  You might want to drill an 1/8 inch hole through the hinge and door before you remove them to help realign.  Then just remove the inner door panel and the hinge cover and remove.  If there is any wiring for power windows, it is fairly easy to disconnect.  There is no special trick to reinstalling.  Just close carefully and make any necessary adjustments.

If you want to remove the hinges from the body, keep track of the shims so you can put them back.

Good Luck

My advice is to leave the doors on.  They are heavier than they ought to be with door glasses and hardware in them and can be a PITA to rehang and align.

I don't want to remove my doors but I do want to install new hinge pins. Are there any pitfalls to doing that?

I agree with leaving the door's on. You'll open up a whole new can of worms.

BE CAREFUL WITH THE HINGE PINS. YOU MAY WANT TO SHAVE THE HEAD A BIT TO CLEAR THE THE FENDER EDGE. i CHIPPED MINE GETTING THEM BACK IN. I WAS OK  WITH IT BECAUSE I NEED A PAINT JOB ANYWAY.GOOD LUCK.
