Which Rear?

[pistonbroke]

I went with the Mitchel overdrive, For the money and work involved to convert to open drive and later axle it made the most sense. The Columbia would be my second choice. I have been down all three roads over the years, and as stated above hacking up your coup and putting in a 3.00 ford 8" will make your little flathead very sluggish in traffic and no fun on hills. I did this in my 42. The Columbia option is a bolt in and works well but it will take a chunk of change and a little searching . My 38 Lincoln had one. For around the same amount of change you can order your Mitchell Over drive and just bolt it in. It comes with a warranty and is new with all its parts still available if needed.

Your issue wasn't the 8", it was the gear ratio you had in that 8".

If he's putting parallel leaves under it with the stock banjo, he's still "hacking it up" and might as well put in a more reliable rear axle (that uses modern hub bearings) that has a wider availability of parts.
