early A body engine swap
the 2266 mts are a strong 13/16" tall & the 2710 is 1&3/4" tall both unmounted. I will see if I can find my measured dimention for the OE v8 insulators #2465508 (bricks) but iirc the OE mts are slightly taller than the 2710. EDIT OE bricks 1&9/16" tall, slightly less than the 2710.
