[Vwdiesel] searcher deficient

[K. S.]

I'm not very good at searching archives so if this is a duplicate of an old post I apologise.I'm looking for information (some I can find) on my volkswagens engines. Ive found data about most of the questions ive been looking for but...
 Do the B series cars use the engine at the same degree of tilt as an A series car? I know manifolds and the like have to be dealth withHow long front to back is the D24TIC engine? 
Are there any recommended companies with engine swap adapters for VW. Many of them are interesting but particularly ones like watercooled on beetle transmission. Or do adapters come up on market forums regularly enough to be worth watching?Over the years ive acquired quite a few piles of bits and peices from several different vw's and other cars.
