Just got done reading through your build, great progress for sure!
It is uncanny how similiar work we did to our trucks. I had to do the exact patch work to my cab. lower cowl to inner cab corners. and the bed liner idea, I felt that was the most durable solution to go with. Hoping it lasts a very long time.
exhaust is slick. Gives me some ideas on how to address my crappy exhaust setup.
Keep plugging away! I'll be keeping an eye over here
