T5 transmission to Slant Six OD bell housing adapter

Yes, their Bell will bolt directly to the slant six. I used the stock flywheel, the stock (although new) pressure plate and used a new clutch disc from a Ford 2.3 Turbocharged Thunderbird. The clutch disc measures the same thickness as the stock slant six disc and the 2.3 has the correct spline for the input shaft of the T5 I used. The clutch disc for the 2.3 is 1/4" smaller in diameter which hurts nothing. The 2.3 produced around 190 horse power which will handle much of anything the slant six can throw at it. Stock disc have been known to handle in excess of 400 horse power with no slipping. I machined my pilot bushing out of oil impregnated bronze. Any machine shop can do this if you don't have a lathe. I don't know if it was my initial mismeasurement or not but I had to take I believe it was 190 thousandths off the snout of the T5 so it wouldn't hit the clutch disc. I also used a Tilton Hydraulic throw out bearing which made the installation easy. A hydraulic clutch master cylinder can easily be bolted to the firewall and line up with the clutch pedal. Tilton does recommend you use a diaphram type pressure plate but I couldn't find one so used the Long style pressure plate that the stock slant six uses with no ill effects.

That's it in a nutshell.
At one point I time QT had a blow proof bell that would bolt up to a slant, but that bell was discontinued and is no longer available. Is that the QT housing that you are mentioning?
