WTD TO BUY - the crank extension shown w/ harmoic balancer

[daninnm]

I do not need the harmonic balancer I have two.....(building two GMC 270 engines)
I need the 'snout' that goes into the timing chain cover and has the harmonic balancer inner ring bolted to it........this is the part wiht the hand-crank notches in the front. I have included a side and front view of the 'snout' or crank extension....anyone.
Need this item badly....
