Lockup to non-lockup question(s)

Thanks guys, remember we spoke a while back Charlie about the crank register? I got a piece made/machined to fit on my 67 converter to match the 70 340 crank.
At my age it is hard for me to remember who I spoke to about what. I forgot you had the later engine. I was just going by your initial post which just stated the year of the car. But maybe my post will help someone else.
