drip rail question

[1972BackInBlackC10]

the previous owner hacked off the drip rail on my truck in an attempt to "shave" the drip rails, he cut them completely off on the doors up to the windshield, and cut the lip off the one above the windshield

i have a parts cab that i got ith my swb frame i bought that has good drip rails, was wondering if it would be easier to put them on or if i should just finish the previous wners job the right way, i have heard that the windshield drip rail isnt easy to shave and is exensive to have done

id rather have the drip rails but with my budget i want to go with whats easiest and cheapest, first two pics are of his lovely bondo job to hide the hacked drip rails, last 3 are of his work, i can get better pics
