NA/NB Crankshaft snout diameter
 
Hi, I am just curious if anyone has the snout diameter for the crankshaft where the harmonic balancer bolts on. I am wanting to use a miata balancer on a different engine because of parts availability and the convenient design.
This is the diameter I need:

Quick n' dirty measurement on a stock pulley I had at hand says 27mm

Ok! Thank you. My crank is 25mm... ofc cant find anything like that, but I think machining a pulley boss is the way to go for me anyway
