HELP TH400 issues with the shift linkage. What do I miss here?

[500/600]

Mine was a 3.8 Chevy and TH200C. For a short period of time I installed a TH400 and the same linkage and mount fit with only an adjustment of the bolt.

*UPDATE*
Well, since the eyelet of the pivot bracket is off by a few centimeters, I am now back to metal works, and I started to recreate a new pivot bracket by using a scrap one...

there has to be different shift rods. i have two of them for a g-body and both are different and the one i'm using has been slightly modified. my dash indicator for the gear selection is off a bit but i'm getting tired of messing with it right now and i'll revisit it this summer to make it better. everything works good now but i think i can do better.
