A 10.5" clutch usually has a 130 tooth flywheel, and the 11" one, assuming it's a true 11" and not the 10.95" one, has more teeth.

Bought these a few years back from Summit and am now just getting it all together. The starter will not come close to engaging so after checking, my old one was indeed the 143 tooth and 11.0" clutch. If I want to use the new set-up, could I simply change the bellhousing? It may cost more to do this than to just buy the correct parts, but I hate to just put these on the shelf. Had them too long to ship back.

I would try calling summit and see if they can exchange the flywheel or kit especially if it's still a current offering. they have been quite accommodating for me in situations like this www.tandmautomotive-omaha.com

Brewers or possably passion are good sources for the bellcrank/mounts and info.

Brewers or possably passion are good sources for the bellcrank/mounts and info. You are going to need either an aftermarket 143 tooth flywheel that has both pressure plate bolt patterns or a bell housing for a 130 tooth flywheel. Brewers has both. Not a huge difference in price. Which ever way you go you may be able to sell yours on Moparts, eBay or Facebook. In theory, there is no difference between theory and practice. In practice, there is.

Under $100, less shipping and tax, from Rockauto Is that internal or external balance FW? Interesting only listed for trucks. Yes, I ran a flywheel in my Diplomat that was only listed for Dakotas. Same 130 tooth flywheel as the cars used. Lots of application issues these days, not just RA though, it usually the manufacturer. I did try to look it up at the LUK site, no help there. As for a cast flywheel, isn't that what Chrysler put them? Some people think everything is a race car out there.

As for why it is for trucks only is probably because only truck 318's got an 11" flywheel (143 tooth) during the years it is listed for. Passenger car 318's would be a 10.5" flywheel (130 tooth).
