Thanks for the reply.

So, the inner panel is crimped or soldered or welded to the cab...

When someone replaces the roof panel entirely, then they need to deal with the inner panel too I guess.

The roof has lots of small dents (as purchased) and would be easier to work from both sides, but I guess paintless dent repair and weld-on studs (plus a little body filler) will need to do the job.

Thanks.
