Sir micheals makes them for sure..Dunno if Grant does Im sure they do.
Go to your local sheetmetal shop and they can make a cardboard templete and have it bent for you. I've done that before and it cost like $80.
Grant! Roll pans are like $70 or so.
get one from grant. got one on my max and it fit great. on grants website they have the rollpans listed under dodge d50 though, but they do have them.
