beautiful work Doug. this kit will be one of my first purchases for my coming build. Starting from scratch with new Ashcroft everything and no donor selected, would there be any preference between long or short?
Let me install one and I'll let you know. Picked up the HD Mopar clutch kit and having the flywheel drilled and tapped for that this week. Hope to finish a project and ship it and get into one of these in the next week or so. Have all the parts on hand now.
If trying to decide, I'd say it depends on what floors,tunnel, and seat box are in your donor I guess. My only concern @ present is how the big slave Chad chose will fit inside the little lt77 trans tunnel. Wont know if its a concern till we have it in the truck. Not much of an issue given the multitude of options
Had time tonight to look into the clutch setup. There are various 1"x 23 spline clutches from Dodge in the 70s. Found a 12" from the 75 W200, and 10.5" and 11" from the 77 Ramcharger. The standard bolts on the Cummins flywheel for "stock" clutches are at 12.5" diameter. Seems a little tight to get the 12" in there, but maybe. No local parts store has a 12" kit in stock to try. Chad mentioned the 11" HD kit from OReillys. I tracked that back to part number K1877-06HD. That crosses with K1877-06, MU5505-1B (alternate NU5551-3), NCF 1105016 at various retailers in non-HD form. There is a Duralast kit in town at an Autozone (NU5551-3) that I may go look at. I'd have to order the specific HD kit, none local.
Doug, do you know why the non HD's don't fit according to Chad? I see several different pressure plate designs across those part numbers so that's my only thought without having them hands on. But Chad posted pictures on his company facebook page that have the thickest of the plates (at outer edge)... so I'm confused. It's no big deal to stick to the one kit, but if there are options it would be good to know.
The clutch fork/slave parts all appear to be from the 96-08 Dodge Ram. That slave is huge!
So the JC Whitney kit was a scam. They sent me the 10 spline clutch with the wrong part number. After spending an hour on the phone with India after hours JC support, they do not have the 23 spline available even though it says in stock and I ordered the 23 spline. So wasted a week waiting on something I have to return. I ordered the MU5505-1B which is supposed to be 23 spline but they sent the MU5505-1 which is a 10 spline.
But the pressure plate is ok to check bolt patterns.
And BEHOLD, 4 of the 6 pressure plate bolts line up exactly with the Cummins flywheel bolt holes. The other two are wide open to drill in fresh steel. I only took photos of 2 on opposite sides of the flywheel.
This might have just got a lot easier. I still need to check the cover clearances inside the new bellhousing just to be sure and I haven't gotten the new fork from Quickdraw yet.
There is an HD 11 inch kit I can order from OReillys for $168 that I'll try next now that I'm confident with the bolt pattern, but there should be cheaper 11" non HD kits available from other manufacturers in the $100 to $120 range. The local autozone has a 11" non HD kit in stock from Duralast part number NU5551-3 for $137 which looks like an identical pressure plate to the kit in the photos below. I used a 1977 Dodge Ramcharger Base with 5.9L 2BBL as the cross reference vehicle, but there are a ton of places this is used. I looked for a lever style pressure plate.
