t-5 questions

[jansen29]

Does any one know how to change over to a 5 speed without using the spacer in the back of the crank? That is what I am using now. Also is there a replacement flywheel that doesn't weight as much as my motor . I have 147 ring gear, any help would be great.

I had a friend tell me that a 1994-1995 trans has input shaft that is a inch longer and there is no need for the spacer then and it will work with the bell housing I have. Anyone know if that is correct.
thanks

The 94-95 t5 is longer and people do run without the pilot spacer but it is still slightly too short for the mII bell. You also want a lighter flywheel? If you are not using headers just use the whole 94 setup with larger flywheel and many choices. I have heard people getting headers around the larger bellhousing with a big hammer.

this tells you the different diameters.

All of the MII flywheels are a bit chunky! Even the 2.3L flywheel.

Don't forget the balance difference between the '78 302 (28.5 oz.) and the late-model 5.0 (50 oz.). Any swapping of flywheel or flexplate between the two has to take this into account.

Rebalancing a flexplate is really easy as the weight is just spot welded on and so can be cut loose and moved. I don't think that I've heard anyone rebalance a late-model flywheel for use with a 302, but it can be done. That said, any early 10.5" diameter, 28.5 oz balance 302 flywheel should fit your MII 302 with a late-model bellhousing. Just use the correct clutch for the flywheel. You should also double check ring gear/starter spacing.

Personally I would have the pilot bushing spacer made if I was doing this swap. The machine work is minimal and any shop with a lathe and a press can do it cheaply. Just use Darryl's measurements from here: http://www.mustangii.net/t5swap.asp

I wonder if the early Mustang T-5 shift handle that some of the swap people sell would be helpful in a MII to clear the dash. It has a much more bent handle than the Fox T-5 shifter handles.

How about one of these:

That shifter gets the job done, but its not a very elegant solution.

Here is the shift handle that I was referring to: http://www.mustangsplus.com/Merchan...P&Product_Code=06089&Category_Code=t5_shifter

The one above (and pictured) does not have as sharp of a bend as I remember. I recall a friend in high school with a '67 or '68 Mustang 4-speed where the shift handle was nearly parallel with the floor in 4th. A little less bend than that (but a little more than the shifter pictured) would solve our dash clearance problem with a T-5 swap.

Yes the 94-95 is just slightly too short for the II bell housing.

D&D in Detriot told me the minimum the input shaft should be in the crank bushing is 1/2 inch. Based on my measurements I needed another 1/4 inch.

I had the bell shaved on both sides by 1/8 inch maybe a little less. The other issue I saw was the use of the input shaft with bearings instead of impregnated brass. The input shaft would have just been riding on the bearings and surely would have damaged them a lot earlier with that little surface area.

I pulled the bushing and installed a impregnated brass one. The local parts store found me one with the right dimensions inside and out. I left it out of the crank by about 1/8 inch to pick up a little more surface area.

The 94-95 T-5 also placed the shifter in the stock location. I had to cut forward an inch to allow the Steeda shifter based to fit up through the floor. I suppose a stock shifter would not have had any problems. Fits in the console perfectly.
