Hey MikeB,
While I do not know for a fact whether Mr. Rodman has the patterns for a "'29 Sedan" in stock, I do know that Chevrolet made three different versions of a 4 door Sedan in 1929. So, you should be more specific when talking about this body style. Probably, you have a JOB NO. 8850 Standard Sedan as there were a lot of these made in '29. Maybe you have a JOB NO. 8910 Imperial Sedan, or if you are lucky you have a JOB NO. 8860 Landau Imperial. This is a rare model indeed. We have just shipped a partial Kit of wood frame parts to a gentleman in Mexico who has this model. Whichever you have, I hope you do a top-notch restoration, and again, when asking around for parts for your car, be specific. That is, have your JOB NO. at hand.Bill/KC Wood MFG
