The main cap bolts are 3/4", six point; standard stuff. The rod cap nuts
are 1/2" twelve point.
To swap 18V engines between pre - and post- buggy bumper cars, you need to
change the two engine mount brackets, and the front engine plate. The ears
on the plate where the brackets attach are in different locations. There is
only one other minor "gotcha". You must use crank, water pump, alternator,
and air pump pulleys that are matched. The change from small to big pulleys
happened at the 77 model year. If you change the pulley size on the engine,
you will need to change the timing cover; especially if you're going from
small to big pulleys. The small pulley timing pointers will interfere with
the big pulley.
