geez i thought it was .090 on sprk.
with -.020 at chuch gear thrust wash. .232 vs .212

for a total of . 070

if either sprkt you have is aftermarkt, you cant trust that any thing is correct on them.

and the real way to check is from the 6 lands at rear of mainshft sprk splines, where the sprk buts to when nut is tite, to sprk centerline.

Yes if you had a nice flat washer that fit into the seal bore against the 6 splines (like DICK mentioned)& sat proud of the inner shoulder, you could just measure down to the sprocket face to get an exact comparison sprocket to sprocket.
