999 lock up clutch wire

Do you happen to know if the A500 converter will work for the 999
I’ve looked at the specs and 26 spline count. They are all the same but the part number is different...very close.

Have you seen the kit by uscartool
67-75 A-Body 518 Crossmember Kit
I saw one just a few minutes ago. If I had known that. I would have just put in the overdrive transmission. Probably would have cost the same except that my 999 is now completely rebuilt. I still might go that route in the future and have overdrive. Depends on how much i drive this thing

Sorry I don't know for sure enough to point someone in that direction on the converter, but I bet a converter place would be able to confirm that.
With a different part number something has to be different though.

I have seen the US cartool crossmembers, but I didn't get one because I was able to easily modify my OE spool mounted.
Lockup alone makes about 300 rpm difference, so just that will help a little bit.
