Pat,
Guess Garry answered most of the questions. The bellhousing needed to use a T-5 is from the Essex V4 engine. Rare as hen's teeth but there are folks who make conversions. I think Minilite is the only wheel company that makes 15" in the "4 on 3 3/4" bolt pattern. I've just switched to "4 on 4 1/4" bolt pattern with new front alloy hubs. The rear just has to be swapped back to the 4 1/4" centers by moving the studs to their original position. Now I'm mounting 16x7 wheels with a 4 1/2" backspace.

Dear Don!
I am looking for higher gears to improve highway cruising. The existing unit is a Salisbury with 3.58:1 gear ratio. I need 3.0:1. Is the differential the same as 6 cylinder Ford Falcon and Mustang? If not, where can I get the gears? Has anyone ever done this modification? I am currently looking for 15" x 7" wheels to replace the Minilites (13 x 8 and 13 x 10) for which I cannot get tires anymore. I have already purchased P205R50-15 for the front and P225R50-15 for the back. The front wheels will do with 0.197" negative offset while the back require 2.195" negative. I am expecting some information from Minilite Wheels in the U.K. I am prepared to make my own wheels if need be.
The next improvement will be to either replace the second gear ratio of 2.214:1 with 1.950:1 or fit a modern T5 5 Speed. Do you know where I can find the gear? Will a T5 fit the existing bolt pattern?
Best Regards, Pat Emery 5365

February's "car of the month" is Andy Seward's Mini Marcos, located in
Pennsylvania.

Hope you all are having a good new year. We will have some more cars on the
road this year with Dave Barton and Bob Magnotti nearing completion of their
rebuilds. Mine is undergoing the change from 13" wheels to 16". Also got a
bunch of parts from Garry Diver (Marcos Parts USA) when he passed thru
northern California on his round trip of the country to deliver parts, cars,
etc. Now I've got something to do on these long winter nights...
