I will probably go at the cover with thinner or reducer once I can confirm this isn't original. We don't need another gas tank mishap..

Up next is the heater assembly inner. I'll have a follow up with details of the blower coil and bracket as well as floor duct.

Note the #7 on the box. The tank had 20. mixing of assembly parts as they don't really matter as long as its a non big block or A/C. Idk what it is at this point but documenting it nontheless..

The inner box does have that textured finish like the dash top to note as well. And yes I do plan to soak it.
