Oh I wouldn't call it a pissing contest, just another day at the office. No doubt I personally would go with Kirkham over ERA, PRICE being the major factor there.
But I'd rather walk than own some of the replica's I've seen, even if you gave me them for free.
I see Kirkham has recently adopted CV joint axles, I'm disappointed, another move toward modernization is better I guess. Sigh,,,
No question there IS a pecking order among the various manufacturers. All though some may adjust where any given one lands on the chart, most would agree to the basic premise. Shelby, Kirkham, ERA, oops, I mean SPF, uh oh...
