Re: TD spark plugs

Bob,
One word of caution if this is the first time your replacing the 
plugs, check to see that it is the original head. Early heads had the 
1/2" reach, later plugs used the 3/4 reach plugs. I've seen later 
heads running 1/2" and 3/4" hitting pistons in early cars. 
A Bosch equivalent plug for your L10 is the W145T1, KLG is F50, Lodge 
is C14 and NGK is B4H1.
I use Champion N9YC(extended tip,copper3/4 reach in my late 53TD).

Hope this helps,
Dave Houser
