I hurt the clutch in my car and have a few questions about related parts. Please. In the picture, the pieces that got loose, what are they and what were they supposed to do? That they stopped doing. Not every spring has one about a third biased to one area. How do you tell the difference between the 11" and 10.95? And, how many of you use the long finger type pp? Tired of paying for and then actually doing clutch stuff. It's heavy. Durr add the picture.

Most mopar replacement applications use the Borg Beck type pressure plate as you have, I have never seen a long type used . Some after market manufactures sell the diaphragm type which is what I use . The 11"' or the 10.95" is more of a manufactures thing , both will work , That's less than 1/16" difference. Can't say for sure about what broke in your pressure plate, scrapped the old one I had a couple of years ago, It had a pivot bolt break hat caused one finger to drop tension.
it's ok to butt heads, just don't do it with a butthead

11" pressure plate has a 12 5/8" bolt circle. 10.5" or 10.95" pressure plate has an 11 5/8" bolt circle.
I use Mcleod 360951 B&B/Long 10.95" pressure plate. This model pressure plate has long style fingers with adjustable counterweight. (The picture below is for a slightly different model without adjustable counterweight.)
Mcleod 500 series ceramic/organic disc or 600 series full ceramic disc. (note that all Mcleod 11" discs are actually 10.95")
I also use a Mcleod Aluminum flywheel.

OK, basically you got 2 different flavors. 130 tooth flywheel(think 1970 and on) takes a 10.5 OR a 10.95 "scalloped" Pressure plate.(bolt pattern) I like the 10.95 as you get a little more surface area squeezed in that bolt circle. 143 tooth flywheel (think 1969 and earlier and most gasoline dodge trucks)take a "full size 11"pressure plate. McLeod 3 or 6 roller borg and beck style street/strip units are good.Their 800 series kevlar faced discs are also good. hard to see in the pic, but the disc appears to have got hot and maybe melted the urethane out of one of the center hub springs? If this thing IS getting that hot you have slippage, and maybe need a unit with a higher static load, and 3 or 6 centrifugal roller assist depending on how high you rev this beast.
I'm 55 now, no time to waste. Not a week goes by that I don't hear about someone passing on.Let's get out there,smoke some tires,have a beer with a good friend,do what you have always wanted to do.I am pretty sure no one will ever say on their deathbed "gee I'm glad my life was calm and boring"

Thanks for clearing up the size difference. Sixgun you're right it is melted, I hadn't looked that close. I let the local speed shop guy pick my parts this time and he went with the McLeod pieces you guys mention, I'll give it a try. Thanks guys.
I can't afford this.

GoMango, how do you like that ally flywheel? Is the car street/strip? What weight/gear ratio/trand/motor do you run?Common talk has always been you need the weight of the 30-40 lb steel wheel to store energy to get the car moving,but having never DONE it, I wanted to ask someone who runs it? Not to argue, but unless they are obsolete, I have had many mcleod full size 11" discs that won't fit a 10.95 PP or even in the bolt pattern.I forgot too, to stress our friend here needs the special PP bolts for the 10.95 setup, else standard bolts will hit the edge of the disc when installed/run.
I'm 55 now, no time to waste. Not a week goes by that I don't hear about someone passing on.Let's get out there,smoke some tires,have a beer with a good friend,do what you have always wanted to do.I am pretty sure no one will ever say on their deathbed "gee I'm glad my life was calm and boring"

When I bought the current disc I called them and asked why their website didn't show any 10.95 discs. They said that any of their 11" discs are undersize to also fit a 10.95 Pressure plate. I ordered one and it fit. I suppose they may have changed them to reduce inventory.
I have this setup in a Street/Strip (mostly street) 440 ebody. There are no lightweight parts other than headers but there are also no options. So maybe 3600lbs? 4.30 gears, 275 drag radials (28" tall)and Caltracs. Absolutely no problem driving on street with alum flywheel. With a smaller engine or 3.23 gears a steel wheel would probably work better. Your experience may differ.
In theory, there is no difference between theory and practice. In practice, there is.

What part of the pressure plate does the term scalloped refer to?
There are notches on the edge of the plate to clear the bolts. And yes the bolts have smaller heads.
