C3 Floor Pans
 

I have a 76 C3 that went o the assembly line in 75. It was finished in 76. The floor pans are half fiberglass and half metal. The metal is were the seats sit. That portion is rusted out. The front is fiberglass. How can I fix this and has anyone seen this before?

Could you please post pictures.

Welcome to the forums. Yes this is a common problem with C-3's and most steel floor vehicles in high moisture areas. You can replace the floor pan or cut out the bad sections and section in new metal. You can also remove the metal and use it to mold a fiberglass section to replace the metal section. You have options.
