Thread: Model A frame mod's and axle?

Tweet

I can't help much but my Brookville frame came with a 2 1/2" kickup at the rear based on rectangular tubing. After I had an original A frame sandblasted it came back looking like lace so it may be a good idea to check some rust spots with an ice pick or wire brush before going ahead. The only potentially useful comment I can make in agreement with the above is that the 1974 Maverick 8" rear I have does seem to fit exactly under the A fenders but you have to use 3 3/4" offset on the wheels so you can get the rear right but the wheels have to be right also. The total width of the '29 fenders is 66", stock. It will probably be expensive to have the 9" axles shortened, but apparently there is a better selection of gear ratios available for the 9". The Speedway catalog only lists 3.00, 3.55, 3.80 and 4.11 while there are many ratios available from 3.50 to 6.50 for the 9" if the object is to go racing. I found one site that does offer a 3.25:1 8" pumpkin for a mere $750 or about $1250 for a 3.25:1 with positraction; I guess I will stay with the 2.79:1 that came with my Maverick rear and play games with the transmision gear ratios. It looks like the 2.79:1 ratio is close to the 2.73:1 in the 2004 Corvette and with a 700R4 the low gear of 3.06 and 4th gear of 0.7 the 2.79 rear does not look too bad and may offer acceleration in low gear AND good mileage in 4th gear; then there is a 3.55 gear available.
