Hot Rods Finding a 1929 Ford Truck Hot Rod

It's a long shot. A hail mary. I'm looking for info anyone would have on a hotrod my late grandfather always spoke of. The license plate for the car was 1R7460 and was owned by him in southern california in the 50s. This car was taken out to Bonneville on 5/15/49 and ran 105.15 MPH.

ANY information or tips to find something like this would be appreciated!

Try again on the photos. They didn't show.

 

It says we do not have permission to view this album.

 

I'm officially confused.

 

DITTO ^ ^ ^^^^ ^

 

On top of that it's a 31 roadster not a 29. Really confusing thread. Besides that it's a beautiful car.

 

I'm guessing Roguss knows a very little about the old cars. He just knew his grandpa had a Model A hot rod and wanted us to find it. So, has anyone seen the car in the pics?
