If anyrhing u should be looking for 3.90s or 4.10s. Why go to 3.33s?

For land speed racing not for road driving

I found that the older series 1 ( early version ) Dana rear with 3.07s was much easier to locate. I also believe its a little bit stronger case than the later Dana units. I used it in the 150 class in the Nevada Open Road Challenge in 05 and it worked just fine.

A speedo correction gear for the trans might be available through Mark Haibeck.
If that isn't available you can go to the site "Procrastination Racing" and look at gear ratios that do the mph conversions with rear gears, tire height, and trans ratios.

I believe I have a set of 3.07s for a D44. I know I had them, probably still do amongst my C4 stuff
