I have a 1956 F100. I need to know which bell housing I need to adapt a late model tranny.  I know I need a car bell housing but which one?  How about a part number?  I am guessing I will have to fab up some motor mounts or do you know of any that I can buy and weld on?  I am still thinking about a tranny (I have replied to a post on this site but my topic search in my profile does not work for some reason).  I have also heard it is necessary to drill a hole in order for most Y blocks to accept a manual tranny?  What are people doing for driveshafts?  Any info is appreciated.  Thank you.
