Urgent: fitting later exhaust manifold on '37 115c

Posted by Ken_P On 2015/8/15 17:02:06

I have a 38 exhaust manifold that I am installing on a '37 115c. I pulled the two outermost studs, because I read that those aren't used. Are the next two studs used, and if so, how? I cannot get a washer or a nut on the stud due to a lack of clearance with the exhaust manifold.

To be clear- the intake/exhaust manifold combo is held to block right now with nuts on the 4 center-most studs. The gaskets seem tight, but I would hate to blow out my good metal NOS manifold gaskets just because the manifold was installed incorrectly. Do the '38s and on really only use 4 bolts?

Any advice would be appreciated - trying to get the car running this weekend.
