i got a digital vanier some where, but i dont think theres anyway for me to acuratly measure the inside diameter, ill see if i can find it and get some pics

I have reading fail :loser:

I ended up getting a different set just incase. Either one will make a good shelf ornament.

Measured the small end from my Crankshaft depot set with a 3-point micrometer. Somewhere between 20.00 to 20.01 mm.

Mine went off to the engine builder last thursday so ill report back his findings once he calls me

Any new info?

The builder said they were almost perfect. Zero issues other than weight matching just a tiny bit. It looks like I got a set of winners
