Recently purchased a 1978 Porsche 924. While working on it, the distributor started showing signs of its age. I already own a Master Blaster 2 and I'm planning on putting in a MSD 6AL. I'm wondering if there are any good distributor options, as the aftermarket for the engine (VW EA831) is almost nonexistent. If needed, I can rebuild internals to fit, just want to know which distributor best fits. Thanks in advance!
