All A-series engines use the same Engine Bell-pattern. This means any rwd transmission, from B10 to B310, fits any A-series engine. No other Nissan engine shares this pattern. This means transmissions from Datsun 1600 or any other will not fit an A-series engine. Note that the only A-series RWD transmission to use an actual bellhousing is the automatic, all the manuals have the bellhousing built into the front half of the transmission case.

Overview

B110 used a dust cover

B210 used a rear engine plate

Engine-to-transmission flange dimension
315 mm: distance between top and bottom bolts
300 mm: bolt circle diameter (11.8 inch)
100 mm: distance between bottom bolts
106 mm: distance between top bolts, offset 5mm from centerline
Starter at 3:30 looking at rear of engine
       (at 8:30 looking at transmission)

Dimensions

E1/J

E1 (1200) and J-series have the same block bolt pattern. However, both engines use an intermediate transmission plate, so the transmission pattern may differ.

J-series and R-series engines both used F4W63, length unknown. Bell pattern differs from L-series. Are J and R compatible?

L-Series

L-series bells are the same six-cylinder to four-cylinder

L-series will interchange with Z-series, but L has considerably more slant. Best to use the correct one.

KA has no slant

A-series has starter at about 8:00 O'Clock position
L-series has starter at about 9:00 O'Clock position

E/GA

E-series and GA-series bell patterns interchange. It is similar to the A-series and will bolt to an A12, but some of the bolts do NOT line up.

Z/VG/KA

These are all identical.

NOTE: L-series is same but slanted. 

CA

CA16 uses a smaller clutch & gearbox. 
CA18 & CA20 use a factory adapter plate & larger transmission

SR is reportedly compatible with some minor differences.

GA is compatible with the CA bell (less adpater)

R/H/U/SD

The SD engine bell is the same as all the R, H and U-series engine (R16, H16, U20). They share the same block.

QR

RB

RB lines up with some, but not all KA bolts. The top 3 bolts are in a different location. RB20 bellhousing on a KA block, the dowels line right up, and only 2 bolt holes need to be modified, one of them is extremely close.
