Measured on the right hand motor in the post #38, I get the following dimensions:
A - centre to centre of mounting screws 4-11/16"
B - overall length 5-5/16" for the wiper casting, 5-3/16" for the bar holding the support tube
C - width of support bar 21/32" (mounting tab on motor casting 39/64")
D - thickness over tin shield and mounting bar 2-5/32"

E - D minus the support bar ~very close to 2" tin cover to mounting feet, but the dimension varies depending whether you measure to motor mounting feet, motor lid or motor body

F - width of tin cover 2-5/32"

G - height of tin cover 2-1/4" (dim. from top of tin cover to bottom of wiper bowlcasting 2-1/2")
