Direct Drive Starters: 392 vs 66-69 426 4spd

Other than the position of the solenoid with respect to the mounting holes, is there any difference between the 1957-58 392 starter and the 1966-69 426 4sp direct drive starter? From what I've read, they both used a 172 tooth flywheel.

I have a customer who wants to know if our 66-69 426 4sp starter shown below will work on a 392. I don't have a 392 starter to measure but from photos I have seen, it looks like it might work since the solenoid can be rotated on our starter. Anyone know if the bolt pattern, register diameter and pinion stickout are the same?

Here are some approximate measurements. The bolt pattern : 4.175 inches
Register : 3.25 inches

The real problem is that the 392 crankshaft extends out of the block more than the later model (post 62) engines.

Thanks. The register diameter on the 426 starter is about 3-1/2" so it doesn't look like it will work anyway.

Thanks again for the info.

The starter ring gears installed on the flywheels are different. They also have different teeth patterns.

The direct drive starters are also way too expensive to use.
