Who has done a 5.7 with a833 4 speed Overdrive ?

Hi guys,
Looking for some input from those who have recently swapped a a833 4 speed with a 5.7 hemi into a 74 Duster. I'm familiar with most tech on what to do like trimming the input shaft, specific flywheel, hydraulic throw out etc. Just looking for general suggestions on what to do/not to do on this swap.

Out of all my searching I couldnt find much which trans mount will work or if I need to modify the Holley mounts they designed for the 727 etc.

Also the last thing is I can't find much info on if I can just use the timing cover on the factory 2013 5.7L truck engine from a 1500. It seems like the alternator location is on top so there shouldn't be any issues with clearance?

Thanks for your time!
