Cab12 Radiator brace bar? Measurement overall?

[Tony Smith]

Although this thread has had a happy resolution for Alex, can I stretch it out on a little tangent?

The brace bar IN FRONTof the radiator grille, as seen in the picture in the first post, was this a CMP-only part, or did it utilise a stock off-the-shelf Chevrolet part?

The reason I ask is that a Chev repro-part supplier, the Filling Station, list several fender brace bars that have the same appearance as the Cab 12 bar. They don't however cross reference the original Chev part numbers, or give dimensions.

The prices seem quite reasonable, so it would be good to know if another CMP related part is available from a retail source, or that a scrap yard vehicle donor can supply a period-correct item.

Hi Tony

Shame they do not include dimensions. The bar is quite long and heavy...shipping by size and weight would be scary.

If need be I can measure the bars I have...length / cross section. It would be easy enough to replicate with some basic black smithing skills.... heat hammer and drill. It does hold the "arches" together quite well but the inside behind the radiator brace does pull the nose sheet metal together even better

It would not be unusual for off the shelf parts being used.... they were in rush back then.

We have not seen any recent progress pictures from Alex.......

PS...... check design pictures of 34 to 1940 Chev trucks....... no provision for an external brace similar to the CMP model....

Measured from two cab 12...... bar is 35 1/4 inch long....5/8 round stock
Each end is bolted to the arch bar, the fender and the air vent corner panel.

Bar is not straight but has a one inch raised offset..... bolt head is 3/4 inch.

Photos are on my cellphone and can't find my cord to download...... so photos are coming.

A few pictures worth many words....

Full view

focus on reworked end

offset

location on arch

Note..... the pen is inserted where the bolt would go into the arch, the fender then the airvent sheet metal. The hole is not round but cut out to a U shape allowing some flexibility to the fender.

The end that is flattened is about 1/4 thick...... flat area 1 1/4 long x 1 inch wide....curvature of offset 2 inches.
