Installed on my early 69 Mustang, original front disc, rear single piston disc conversion, 1" bore MC, GM style distribution block, manual transmission (z bar/rod). Was a carbon copy of the original midland that I pulled out of the car. The bolts were all standard thread like the original. Pedal feel is similar to the original one. Pedal is not excessively soft like some people have noted about the midland. At least with my setup. Of course, pedal feel will vary based on your calipers and MC. I give this 10/10 stars for being such a great quality reproduction that was pretty much a carbon copy of stock. WCCC is the ONLY place where I found a repro like this. I discovered this booster through the WCCC YouTube channel. Was tempted to buy a second one to have as backup, in case this goes out of production.

       

I'm in Australia and really stuck for finding a midland Replacement booster, had plenty of experts telling me this will do or this should fit. I didn't see the no core replacement midland at first, ordered one immediately, fitted it no probs, works great, just make sure you adjust your rod that goes into your master cylinder or you will have too much travel on your brake pedal and make sure you bleed your brakes. WCCC turned a big problem for me into an easy fix- thanks fellas...
