R52 Exhaust.

Baffles or not? On my R52 the baffle at the end of the header pipes has the welded on end cap removed, assuming its suppose to have one.

R67 Bell housing

Hello,

I am restoring a R67.
Anyone out there have thoughts on the drive shaft bell housing.
The one i have looks to have been cast with a cast finish and has rectangle hole for install/removal.

Thank for any information.

Number on case

Does anyone out there know what the number cast into the top of the timing case on R52, R62 and possible R11 S1 mean?
Most seem to have a smooth case, but some look to have a 3 or a 4 cast into it.

Thanks for any information.
