Here is an example of what has already been advised. This home made engine stand held an 8BA from the bell housing.. The bolts used are 1 inch longer than the hollow sleeve they fit through. The hollow sleeve is 3 in. long. Any adjustment can be taken up with washers. Bolts are 7/16-14 x 4 in. long. For stability use an engine stand with 4 points of contact with the ground. Also, the larger the castor, the easier it rolls.
DO NOT USE A 3 LEGGED STAND.
