Converter with 1.550” nub builder needed

Has anyone had a builder recently build a customer converter for a pre 67 a-904?

I tried Cope- nope
I tried Protorque- maybe.
Engine is done and cannot machine crank for it is already done and in the car. Machine shop did not want to cut crank as “converters are easy with small register.” Lol! Not so easy.
I am looking for a converter with the small 66’ front register (1.550”) and a rear pump drive for a larger pump 1974 a-904.
Stall needed. I can go 100% 66- 904a but it will have smaller input shaft and pump and nobody has converters for that - that I can find.
