Also your dark brown is most likely cordovan brown. Light tan might be Sante fe tan.
I looked into one for mine. The TH400 was rebuilt prior to my ownership but works fine & has a firm shift. I figured the GVOD would keep things simple. But, the way my carrier bearing & exhaust (3" dual w/H-pipe) is laid out would likely require re-working them to put one in. Plus, w/it being aggressively lowered, the actual GV sump would be near mid-cab which is around the most vulnerable spot in the length of the truck. When your ~5" off the ground w/a ~20' frame length, that's an expensive ouch if it tags anything.

For the cost of each, I'd do a 4l80e in a CC lowered dually.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
