1954 ignition points

Re: 1954 ignition points -- new points don't fit

I just went to the Standard eCatalog at: http://www.standardbrand.com/Online%...g/Content.aspx If you enter 1954 Chevrolet Corvette, the ignition point set that comes up is DR-2227P and the picture that comes up shows the points that don't fit the Corvette distributor. The same points come up if you enter 1954 Chevrolet Bel Air. So evidently there's a catalog error right at the source from which most aftermarket ignition points originate.

This part is listed for the Corvette I-6. All other Chevrolet I-6 for the same years list CS763P.

Actually, the source of the above statement is a 1989 Standard Bluestreak catalog I have that lists the '53-'54 Corvette point set as DR-1823 and all other '53-'54 six-cylinder Chevrolet models as DR-2227XP.

Then I used napaonline.com to cross 1825852/DR-1823/D110H, and they all came up as CS779A, and the DR-2227XP came up as CS763P and CS63P. I didn't bother to look up the application, but it looks like this is one of those application catalog errors that's been around for decades that will never get fixed because it's so pervasive throughout the parts industry. The Bluesteak application guide shows that the DR-1823 applies all the way back to 1932, but the DR-2227XP appears intermittently from '32-'62.

That brings up the question of why two different design point sets were used over these three decades, but I'll let you six-cylinder guys figure that one out.

So order a CS779A and bring your old points with you to compare before you buy. I'll bet it's the correct part.

When searching for an old part I prefer to first try to cross reference an OE part number, if I have it, because errors in the application catalogs are not that uncommon and can spin you into a black hole.

Hmmmm..... According to the NAPA Buyer's Guide for the CS779A, they also fit a 1934 Chrysler Airflow, a 1933 Franklin17-A Twelve, Chevrolet Stylemaster from '46 to '48, a Auburn 12-161A Custom Twelve Dual Ratio, and others of the same era. That suggests to me that these might not continue to be available much longer. Best, I think, to stock up.

One more observation before I put the books back in the case.

It appears from the photos that the D110H (CS779A) and D103P (CS777A) have the same base mounting holes. The difference is that the leaf spring on the former is secured to the dist. housing via the black insulator (see photo in post #2) and on the latter the spring is secured to the point set itself, so if the D110H disappears, the D103P can probably be used by either modifying the distributor or modifying the point set, but if you have a six-cylinder Corvette it's probably a good idea, as suggested, to buy a few sets for the spare parts box.

Duke,
There is no need to modify ignition points. There is a Delco point set that will work. I am not at home so I don't have the number handy but the former 53-55 team leader, Dave Brigham, should have it.

My listing for the 53-55 6 cyl. points are 1925852= D110 i have a early listing 1882391= D110. these are from very old DELCO books. Hope this helps. Kevin
