Bill, I don't think you should widen the caliper once you ground the tabs (and the 'L') off. You risk the pads shifting or falling though when they get low.
Great save!
Someday, I might find a set of the the endplates and go at this again.
One huge benifit of grinding the ears off and making a mounting block is that it will be so much easier to remove and replace, instead of messing with that one bolt burried up in the trailing arm netherlands!

Whoever machined mine didn't do a very precise job and this would also be a candidate for improvement. The clearences at the edge of the rotors are extreemly close.

one of the cool things about 993's is that they come from the factory with 993 brakes.

Yeah, thats essentially what Im turning them into Those don't come up for sale very often.
Well...as it turns out, I have a set off a 91 Turbo if anyone is interested. Had these for sale on Pelican and moved to DC so I never got around to finalizing the deal. $650 and all this can be yours. What you get is the calipers, a used set of rear rotors (with some life left on them), and an older set of pagid pads. These would be just to get going...a little life left but not much more then that. One of the front calipers has a nick in the seal so it would need to be replaced. PM me if interested.

Cheers,
Jeff

Well, I made my decision on how to do it. Theres no going back now The only real decision left is how far apart to drill & tap the two caliper holes...

Bill, The calipers will still be a minor pain to remove. The VCI adapter taps the caliper body and the bolts come up from the bottom - not down from the top like the fronts. There really isn't room to counterbore a hole from the top (the bridge bolts kinda get in the way.) I'm planning on the same way.

Looking Good!
After a lot of research, I found that my calipers came from a 928.
The tube connection on the fronts were bottomless. This means that it is a banjo type fitting. The 928 used flex line all the way to the caliper so I don't have to break any lines if I have to service the hub bearings or rotors. Easy Peasy!

Maybe there is a way to do this on your setup front and rear.
On my rears, I was able to reform the stock 911 rear tubes to make them work.
I had already bought the new tubes etc. But they ended up being too long so I tried this and it worked fine.
A flex line that was about 6" longer than the stock flex line would be perfect!

Too bad you can't bolt the calipers from above like on the fronts.
