I'm installing a rebuilt 1.9 in my 84GL.  When I tightened the 3 belt pulley bolt it wouldn't snug the pulley down.  Closer inspection revealed the crank on the rebuilt receives a shorter bolt.  What gives here?  I live in a rural area and can't find the shorter bolt locally.  Will a spacer work or should I try to order a bolt and wait until next week to continue?  Any advice will be appreciated.
