'65 Dart /6 A833 swap - clutch fork, input shaft, speedo gear, crossmember questions

I have the correct large hole bellhousing for the transmission, but I will need a new clutch fork because the OD bellhousing has a ball pivot. Hopefully the rest of the linkage will line up. If not, I'm capable of fabricating whatever parts I might need.
The Ball-fork to me, indicates a truck bellhousing. If you provide your casting numer to Brewers, He can verify that ...... or not.
