318 poly crankshaft pulley

you nailed it mark, its the original engine in my 65 d100 with 4 speed. i'll get some measurements today. would anyone happen to know what size socket i need for the crank bolt? the biggest i have is 1 3/16 and its too small.
I'll see what I can find when I get back to work on Monday. The crank bolt (if it's the same as a car type) takes a 1 1/4" socket.
