Pressure Plate Problem

Pressure Plate Problem
Installed the 226 today, got the trans mated to the block, and then when I was hooking up the driveshaft I noticed it could turn... while in gear.... (rear end is off the ground)....
Clutch was not connected yet; so I removed the inspection plate and discovered the three fingers on the pressure plate got stuck on the trans input shaft bearing retainer during assembly... creating the effect as though the clutch was depressed.
Hard to take a picture of...
I'm hoping someone will give an easy solution or tell me I did something wrong!! Or if the problem is the PP (from Mac's) then OK, I pull it off and get a new one or have the old rebuilt... Do I need to have the rotating assembly balanced again, cause I just had it done!!! errrrrrr
It's the 11 inch clutch and PP, trans is HD 3 speed.
Thanks

I know the photo is at an an angle so there is a parallax, but the finger at 1 o'clock looks longer than the the other two. The input shaft isn't that big.
It has been 25 years, but I seem to recall I did this on my truck when I was about 18 years old. I slid the transmission in at an angle and got one one finger caught. It was a long time ago and I've slept and drank beer since then. I think I had to reposition it and go in straighter. I had a 10" clutch on a 239 V8. Can you support the rear of the engine and remove and install the transmission working from through the floor pan?
One question not related to the clutch. On flathead 8s, the flywheel bolts are lock wired. Are the bolts on a six not lock wired as well? Or did you use different bolts and just lock tight them? I'm sorry. I hate to be "that guy" of when you post pics of one thing and someone asks something else.
Good luck

Thanks guys;
Ross, I recieved the PP and clutch as a gift well over a year ago (I think my dad was expecting me to be moving a little faster), so unfortantly it's mine forever at this point...
John, I was thinking about it and it may have gone on at a slight angle but all three fingers are resting on the shaft, shouldn't at least one not be?
My plan today is to pull the trans and measure everything, from looking at it though the inspection plate it looks as though the fingers are just barely resting on the input shaft. I may try to file it slightly and see if that does the trick, looks as though theres plenty of material there.
Otherwise the old one will be made new again which is what I should have done in the beginnig. Thanks guys

I'm sure it must just be a mock-up photo, but in case it isn't, I've gotta ask. In the photo of the rear of the engine - is that exactly the way you installed it? Because if it is, I don't see a clutch disk in there and that would be why the driveline can still be turned with it in gear. That would also be why the fingers are in contact with and depressed by the throw out bearing.

Just making sure! .
My dad bought a cheap, offshore made clutch disk from a catalog company many moons ago for an 8N tractor and we couldn't get that thing to play nice with the existing pressure plate and throw out bearing no matter what we did. The thickness of the lining was wrong - way too thick. With the adjustment all the way at its limit, it wouldn't release until the pedal was touching the running board. I finally ended up replacing it with a domestically sourced part and it went in and adjusted perfectly.
My point is that I wouldn't be too surprised if everything doesn't fit right if the parts were made across the pond. Their tolerances are vastly different than ours.

I understood that. No wires. They are "locked" by being torqued to within an inch of their breaking point.

Well I pulled the PP off today and did a quick grind on each finger, put it all back together and slid right on, no touching! Clutch Ops check good.
Glad it was easy, but not quick. Took a good part of the day to pull the trans, clutch housing, and pp; then put it all back together, but it's done. Thank you all for your input and help!
Ps - in case someone notices from the pic above, Yes the rear valve cover is upside down, and two head bolts are missing
