Conversion Information ???

[Grandpas 70]

I have only been in 67-72 community for a few years now after being able to get my Grandpa's 70 Last year at 99 he passed so this truck like so so many others I've seen will be a labor of love. I know he'd smile knowing I'm going to make it my own. That being said... a few years back there was a gentleman that was selling a disc on eBay that had all kinds of information on it from disc brake conversions to relocating the gas tank. All of these conversions used stock parts from other year models.. Does anyone possibly have a copy of that disc or maybe another set of information similar to the one I described. I have looked many times for the disc to be listed again but I haven't come across it again. I thank you in advance for your help and I hope you all have a great day.
