I have my 1/2" plate marked to do the 4 tranny holes that need to be threaded and the 4 studs to go in the holes. It is already drilled for the bellhousing and output shaft extension. I hadn't thought about helicoles but that wouldn't be hard to do. If I go with a newer T5 I will need a piece of 5/8's aluminum to get the correct space. Another thing that is happening with me is another ford guy is interested in the T5 that I have and has a T56 out of a firebird to swap for it. He gets back into town this Tuesday and I may swap trannies with him. If I do, I will have an adapter that is almost ready to bolt in. I would let someone have it for my cost and shipping. Either way I will have a great transmission upgrade that will be fun to drive and save a little gas as well. Right now I'm getting 16 MPG on the highway. I believe Norval and carguy4sure will be posting this project in the next day or so. Be on the lookout for it.

Are you thinking about a newer T5.. If yes don't drill the trany holes in the 1/2 inch plate, it will work fine if you do too. I never went into the 2 plates because I figured you were using the older T5. If you are going with the new one get another 5/8th plate and bore the big hole, the 4.905 hole and the 2 lower holes, one at 8 and one at 4.
Two plates is just as easy to work with just twice the amount of maching.
I found out today that transfer punches don't work marking the transmission hole.
I put the trany on the bench, a 4 x 4 under the transmission mount and put the plate on the front, level the plate and clamp it with 2 C clamps, one on either side in the center. Again a transfer punch will not work so I took a 1 1/2 inch long 7/16 bolt, put it in the lathe and turned a point. This fit the transmission really well and I center punched the 4 holes, also mark them with a pencil for easy identification when taking the plate off. Drill and tap the 4 hole 7/16 coarse and install 4 studs.
We got to the point of indicating the hole on the plate, we were at .008 maximum runout or .004 which to us was not good enought.
We quit until tomorrow night.
Have anice evening Bernie and if you want to talk call me tomorrow.

My trans is about as new of a T5 as they make and I used a single plate. I modified my existing bellhousing so that I could mount the adapter to the bellhousing from inside the bellhousing for the upper bolts.
I didn't think to make a drawing of the adapter plate when I did mine

Swaboltm,
If I don't use the adapter plate I would be glad to sell it to you for my cost. I should know in a few days which direction I will be going. I'm still getting it ready and should be ready to install.
