New addition to the stable - 83 Ramcharger - questions, too

Depends on the rust.

LMC truck is showing blow out patches for the wheel arch. Seems like parts are starting to dry up a bit more than ever. Auto Body Specialties used to catalog small patches forward and rearward of the wheel arch, about six inches or so high. A quick look at their catalog shows nothing, now.

But it might be worth making a call and check to see if they have any warehoused.

You can also try your local paint jobber. Mine supplies through Keystone. I've bought a lot of rust repair patches over the years for a lot of different vehicles.
