67-72 doors

[69ersleeper]

hello guys, im working on my cab right now and im at the door. As I was taking them apart to re-pair the rot, I looked back over them and realized there was alot of rot all the way around, to the point where I feel its not worth the time to repair them. Should I buy new shells from lmc, or try to find a good pair that might need some repair(im having a hard time on it). Would anybody in the New England area have a pair for sale that I can buy? Also whats the difference between 67-71 door panels and doors. I noticed the door panel trims are different, are they also different sizes? Any recomendations would be a great help! Thank you in advance!
