Question regarding starter in small block

Kraby
I just got through putting a new 340 in my 69, with a new minie starter, and I did not use shims. The original 318 I removed had no shims under the starter.I have never seen a small block Mopar with shims under the starter. This goes for the ole big starters and the new minnies.
Chebbies have them and sometimes are pain in the rear.
