    Adaptors came today....might have to do some machine work on the bearing retainer or the hole it fits into. Retainer is too big in diameter...oh well, just another mod to make! Measured the pressure plate fingers and they need to be adjusted...slightly different heights. Can't seem to find an adjustment bolt. The ones I loosened (right over the finger pivot stand) didn't seem to do anything. Left some slop in the fingers and stayed loose....not a good thing. So, I tightened them back up. Anybody got any ideas on adjustment of those 3 fingers?

    Some of the older style Long or Borg and Beck pressure plates didn't have provision for release finger adjustment while others, particularly the Long which Ford traditionally used, had short bolts where the throw out bearing rides on each of the three fingers. A small amount of difference you will never notice - that's just the way they were. You didn't say how much difference you have though. My favorite trick 'way back' was to fill the empty spring spaces or just replace all of them with similar height or a wee bit longer valve springs. I guess that's one reason my left calf muscle is bigger

    Thanks, IC2! The difference is really small, maybe 1/16" or less with only one of the fingers. I guess I'll leave it. Going to look at the machine work necessary this morning in the bright of daylight (and clear head!). Also concerned about the tranny being moved about 5/8" rearward. This pulls it away from the pressure plate, making clutch adjustment even more difficult. Still may have to revise clutch actuation, maybe hydraulic is the answer.

    Verify this measurement (in height difference) only when pressure plate is bolted to flywheel! It could make a difference...

    Update: Got a new B&B clutch from ClutchMasters. It is a 10" and is smaller in size (case-wise) than the 11" Weber I had previously used. There should be no interference with the new adapter case now. The aluminum flywheel is drilled for a Long style or Borg and Beck pressure plate. I pulled the old pp and fitted the new one and the holes line up..!!!! Some small victory finally. Just ordered another clutch disk in the 10" size from Summit. I have attached a pix of the new stuff. I cut an inspection hole in the mini housing to see the throwout bearing clearance from the pp fingers. Also made a little cover for it.

    Took the adapters to a machine shop to get them "thinned" out a little bit. I measured and I need more of the input shaft into the flywheel pilot bearing and more splines into the clutch disk. I'll gain almost 1/4" by careful metal removal. Then, it's just bolt 'em up and get it off the jackstands! Nothing else could go wrong....right? Hmmnnn, we'll see.

    Got the adapter plates milled down a total of 3/16" which gives me enough insertion into the flywheel bearing to work. It also gives me just enough spline contact into the new 10" clutch disc to make it work. The splines are completely engaged, whereas before, they were not making complete contact. Next week, I'll start putting everything back together and I'll have to face the clutch actuation issues. But, it will be some progress!

    Had to burr out some clearance for the 4 bolts to fit into the adapter plate. Was successful. Then I tried to mount the plate and the bellhousing adapter to each other and realized the bolts I had carefully bought were not going to fit precisely. The threaded holes in the plate and adapter are crap! Not SAE....maybe metric? Saw another site and they had the same problem and had to drill and tap for another size. Why the hell is this? It's an Offy branded part...can't they be a precision piece? Damn!

    With a lot of companies, quality control is almost a thing of the past, and understandably so imo. With all the import crap on the market, the US manufacturer's have been forced to cut corners and speed up production just to be competitive in the price game.... Unfortunately for most buyers, price is a much bigger concern then country of origin or quality! In the last 10 years or so I can't really say I've purchased a lot of parts that came out of the box and installed on the project without some tweaking, detailing, and in many instances replacing some components with a quality piece!!!!

    Yea, but I paid $450+ for these two pieces of aluminum. Not cheap by any means. Still think something is wrong with the company that produces this inferior product I've had them milled down to fit my application, so I can't return them. I'm stuck making them work....and I will, but still, I would hope 8 tapped holes could at least be correct!

    450.. ouch! And it "doesn't work".. That's enough to p_ _ _ off the pope!

    Now I hope it gets better soon for you!

    As Dave S said ......

    Can these be drilled and tapped for Heli-Coils? Instead of bastardizing with metric fasteners, possibly those inserts would be your best bet plus your bolting will go into steel instead of soft cast aluminum.

    I can't count the items that I've purchased these past few years with either metric threads or an odd ball wrenching surface - might be 1/4 20, but a 10mm wrench size
