Flywheel ? for the /6 guys

There was a bigger bellhousing on trucks that I believe worked with/6 or small block but that flywheel was much bigger.

That bell housing was used with the NP435 (I think that is the number) trans. That is the 4 speed that has the shifter go right into the top of the trans, with a "granny" 1st gear. But I don't believe it has a dual engine bolt pattern. I have that flywheel and clutch on hand, but no bell housing. The flywheel has the slant bolt pattern.
I took apart 1965 D100 and 1968 D200 slant 6 to get parts for my 1967 W200 (Small block V8). In both slant 6 engines, the bell housing curved beyond the slant 6 mounting surface with exposed bolt holes, so it could be used with the small block V8. The W200 did have the NP 435, shifter on the floor. Both slant 6 trucks had 3-speed shift on column. I remember all 3 bellhousings being the same. I had thought the flywheels were universal because the bellhousings were the same and the small block 318 and the slant 6 were both internally balanced. I remember the starters also being the same. If I'm wrong, OK.

Of course, now, I take hundreds of pics. Then, I hardly ever took a picture. I put a 1970 Grill on the truck. A welder friend made brackets so I could attach a later front bumper. Wish I hadn't sold it.
