Re push rod length.
I just ordered a push rod for my 1959 G12L. I picked the one that says 1959 only obviously.
When it arrived, it was 1/4" shorter than my other three.
I phoned Steve on spares desk and he said did you order by engine date. Yes I sad. Well you probably have 1960 heads on the engine.
Which need the longer rods.
I said it would be good if you put the length of your push rods on the listings as I would have naturally picked the right one.
Cheers Dave
