I had to do them on my 57 LCF. Not only were the pins worn out, but the holes in the hinges also.
I chose the approiate size bit and drilled out my hinges and replaced the pins with the exact size grade 8 bolts. I ground the hex heads round, and they look factory.
I think some of them took a 3/8 hole and pin, and one or two of the worst ones had to be drilled out to 7/16.
Also in some of them, I put a washer in between the two hinge halves, to make up for the "down" wear.
