I was pulling my gearbox on Sunday for a rebuilt so I had a chance to inspect the exhaust.  One of the toilet bowl clips is missing as is one exhaust manifold stud. I replaced studs and used brass nuts previously. I would recommend using flex pipe sections even with the toilet bowl to keep things from buzzing off.

>> Thanks for the exhaust info. At this point, I will keep things simple by using the RV 1.8 exhaust manifold that came with the engine/diesel parts I bought. A person on the samba (Bill) swore by his "toilet bowl" exhaust set up and said the exhaust never had any cracks. Having built at least 3 different versions of exhaust for my 15º swap, I'll gladly sacrifice a few HP for exhaust longevity. .......  I hope!
