Title: 160AX screw in freeze plugs or press in
Post by: steve-0 on January 12, 2011, 08:37:24 PM

at some point they started using screw in freeze plugs in the blocks. one other difference in the blocks with the screw in freeze plugs was that at the rear of the block below the head there is no longer the 3/8" bolts to use as a grounding point so they incorporated that into the coil holder.

I'm reasonably sure my M3 was rebuilt in the 50's. I wonder if that was when they went to the screw in soft plugs? Maybe a conversion?
