I have always just bolted them up, and the spacing comes out fine. There is a lot of lee way in there for the front pump lugs to engage.

In 15 or 20 installs, have never had a hint of a problem. All types of converters and flex plates.

Before putting flex plate on align bolt holes and mark converter and flex plate so it is easy to bolt up. Put converter in transmission till seat into pump, put on motor and bolt up transmission pull converter out till standoffs touch flex plate and install bolts that's it.
Min. clearance 1/8"

xs2 , I have installed more transmissions that I can count and if im having to add spacers and shims and washers there are bigger issues than using a band aid like that. like maybe your flexplate is on backwards. the converter bolts will always pull the converter to the flexplate like its supposed to. or so it seems to me, but what do I know.

Seems this is an engineered dimension and I never thought much of it. There are virtually no variables assuming all the parts are as engineered so the chance of it being wrong are slim. Aftermarket converters would be one variable but pretty sure they got them correct. I just installed one and want to say I pulled it forward at least 1/4" maybe even 3/8". Works fine.

I've worked in the transmission business for years in the past and never had to add shims or washers to the converter. Bolt it up and go. The witness marks iv seen on torque converter hubs have plenty of room for pump gear contact when installed.
