2F to 3B conversion advises needed

[MUDHOLIC]

Hello all mech. and Tech. Gurus, i need your advises about an engine swap from 2F to 3B; current engine is a 2F, transmission is a H41 with 19 splines i think as the truck is dated 1984 all stock/factory.
So beside the engine here it is a list of the modifications that i should have to realize:
Belly Housing
Cross member
Engine mounts
and finally input shaft for B engines.
I can deal with the first 3 but the 4 th one is a major problem to me;
as far as i know i can not use an input shaft from a H42 on my H41 tranny + the donnor is a Bj60 86 or 87 not sure of that then the tranny has to be H42; i can not have the whole drive line, wrecker has already sold the transmission as a chunk, all i can have is the engine belly and may be the cross member.
Can you help me out?
how can i connect this engine to my H41 without searching for a H42 tranny?
I appreaciate any advise, idea, help...Thanks

Cmon guys at least you can tell me whether the input shaft from H42 is interchangeable with H41's input shaft or not?
Or can i use the B type input shaft of a H41 with the H42 spec. 3B engine?
Someone must have the answers...

You need to be posting diesel questions in the diesel forum.

No, the input shafts are different.

Move this to the diesel section and detailed answers will appear like magic.
