where to buy patch panels??

O K i admit i been out off the hobby for 8 -10 yrs now after being in it since the mid 80's. i a dmit i'm that old! last time i was at mopar nats they were just starting to offer some E body hoods and fenders.
went on Shermans site and they asked for sales tax numbers?? i see what looks like nice stuff from the AMD. nice price too.
question, anyone make a decent 72 duster lower qtr patch and affordable or must i fab it???? ADM flloor panels are too pricy for me. i never could afford anything from Year One back in the day too. i don't even have copy of MCG. actually quite that when all they couil;d talk about was mopars at the manshion!?????? thanks for any advice.
