anyone make their own door panels???

Trying to decide stable gun I need to attach the upper metal to the panel. Early B door panrls are not like 66 up!!
The old ones are masonite with an oil . I will use the Luan for the trunk divider for sure. ITwill be painted black to match the carpet or red to math the panels!!! NO back seat remember!?? LOL.
If I had just one car to do, I might would just buy the panels IF I did not spend all my $$ on meat and gas!!!! But that would be TOO easy!!!!
