[TR] TR4 - alignment dowels for the big end of the connecting rods

[Thomas Boggiano (work)]

I am looking for a source for the alignment dowels for the big end side of 
the connecting rod. I dont seem to be able to find them. The housing on the 
connecting rods are out of round  in order to resize the big ends correctly 
I need to remove the alignment dowels from the connecting rod caps. In doing 
so it looks like I will damage the dowels and I would like to install some 
new ones. .  They are 9/16 OD X 7/16 ID X .800" O.A.L.

Can the dowels be reused if they are slightly damaged on removal?
Any idea on where to get new ones?


Thanks
Tom
