Crankshaft Pulley Bolt

I am tearing down a 1275 engine and have gotten to the point where I have to 
remove the crankshaft pulley bolt. I am going to have to order the socket and 
according to my measurements it 1 7/16. Tell me if I am wrong. The guy at the 
NAPA store tells me that it will cost $24. I believe in buying good tools, 
but that seems kind of high. I went to a local Sears and they didn't have 
socket in that size.

PS; As somewhat of a follow to my broken lug saga. The guy at NAPA asks me 
what car I need this for and I tell him  MG. He says you need metric then. 
This is the second time in a week. I tried to tell him the English started 
the English System. Hopeless.
