Right now, I've got a '59 292 in my '30 Model A Coupe.  The transmission is a 3 speed toploader from the early '60s (non-synchro'd reverse).  I THINK it's the wide ratio transmission because there seems to be a big difference between 2nd and 3rd.
The rear is a Dana 41 with 4.27:1 gearing.  The tires are 29.5" tall.

On the highway it's spinning at 3200 or so at 65 mph.  In Second Gear, at around 30 mph in town it's also spinning close to 3000.  

Anyway...I originally thought about getting a 9" rear with more reasonable gearing in it, but then it may not be as fun.  Doing the math with a T-5, with two extra gears, and one of them an OD, I think it would be a better option.  

1.  What would I need to make this work?  Clutch Parts, adapters, etc.?  
2.  Anyone know how much further back my shifter would be coming from a toploader?
3.  Anything else that I'm overlooking?

I don'tr remember the gear ratios of my T5. It's from a 90 Mustang GT and this info should be in my notes or on the net.   I'll look and report later.  I think 30X9.50 R15 LT  30" diameter tires help keep the revs down some. 1st gear is ok but for my strickly street driving I wouldn't want any more than the 3.5 rear that's  in the truck now. 1st winds out prety quick making a shift to 2nd necessary just before conpleting a corner, for example. My adapter is the one clocked straight up but I can't say what would be best for your "A" chassis.
