What a fun project! I have no experience so I can't offer advise but someone will be along soon to help. Good luck.

wow !! what a beauty

What size are your tires? That will tell us about your wheels.

Front brakes are either 1928 or 29 .   rear brakes look like 29  ???

@35mike Wheels are 18".

@prewar 

It would appear to me that much of your chassis is definitely NOT 1930, but probably 1929 as Bruce suggests.

In 1930, the front brakes were cable operated... yours are the lever style as in 1929.

And your front springs have the short "shock absorber" leaves on top of them that were used in 1929 but eliminated (I believe) in 1930 when Chev added actual shock absorbers to the car.

Hope that helps.  🙂

Here's more info from Lou MacMillan:

Speedsters are frequently made from spare parts so there's
a lot of Chevy parts that interchange thru out the years.

From the photos, the front axle is 1928 or 29. (1927 had no
front brakes and 1930 had cable brakes.)
The rear axle could be 1926 - 29 passenger and half ton.
The frame appears to have been sectioned together.

The wire wheels can be determined by their size.
1928 = 21" Most wheels were wood spoke or metal discs.
1929 = 20" Most were disc. Holden still had wood spoke.
1930 & 31 = 19" Wire wheels were popular.
1932 & 33 = 18" Wire wheels were popular.
1934 - 36 = 17" Artillery and Wire wheels were popular.

Hope this helps.  Dean

@prewar I think 1932 was the only year Chevy used an 18" wheel. This information, of course, is not related to the year of your chassis. The Chevy 6 bolt pattern was unchanged for decades.
