I was just kidding as you well know.

uIf you have to buy new stuff, 3:78 are the best all around gears unless you are always going up and down steep hills.

[Mac VP]

The original gear ratios (3.78 and 4.11) were not reproduced, so unless you can find another good used gearset or an NOS set somewhere, you'll have to work with the new gears in the higher ratios. We carry that '34 ring and pinion in 3.54 and 3.25. With the stock engine you would be happier with the 3.54 gearset. We're closed today but call Monday if you decide to order with us.

Just a note .
I have both a 33 fordor and a 34 3w, when the 33 had the original 33 babbit engine it had the 4.11 gears in,it was as smooth as and would run at 60mph no drama,my 34 has a 36 lb engine and 3.54 gears in,its nowhere near as nice at 60 as the 33 was.

Admittedly, I'm no expert on this, but it seems intuitively the opposite of what it should be. Do you have any explanation of why this would be?

if you find yourself wanting a 4:11 gear set for a 10 spline drive shaft, I have one from a low mileage 36 that we changed to a 3:78, had to use an adapter to go from 10 splines to 6 splines for the 3:78. the 36 LB engine really likes the 3:78. what number do you have on the speedometer turtle? 18-3:54, 19-3:78, 21-4:11

I would prefer to stay with the 4:11. If you know of a good used or new one for sale, LET ME KNOW. Car is registered for the Keeneland Concours on Lexington KY in July. I hate to pull a rear from another complete running car in desperation.

[Brewsterbuff]

Sounds great. 37 tooth ring gear, 9 tooth pinion, and 10 spline drive shaft. The Brewster has an extended frame and has a steel plate on the bottom and top of the frame rails, that hides the speedometer turtle. The turtle is on the top of the Torque Tube extension so even with the floor boards out it is hidden by the top steel plate. My speedo was pretty close to correct so I assume that it is correct for the 4:11 rear. Sure would like to get together on the phone. Will try to send a private message with my number. Never did that before, hope I can make it work.

The later 35-48 gears will not work in a 32-34 rear unless some machining is done on the ring and pinion gears. Plus the splined end of the pinion is too long which would require the pinion or the driveshaft to be shortened.

Sounds like the '36 is not the best unless I get into machine work. Have a couple of other replies so I guess I need to check them out.

Is there a way to measure and make sure I get the correct one? I will look mine over for stamped part numbers. Didn't look at them that close for numbers. Frame vin # is 181205754. Most all Brewster were built on the 1934 frame but I will try to check the numbers and make sure.

Thanks to everybody who went out of their way to try to help. I found a set in GA and it arrived yesterday, looks good. Hopefully by the end of the weekend I will have it back together and ready for a test drive. Don
