One of the things I've learned (often "the hard way"); is that when you're dealing with a bunch of committed enthusiasts (read:fanatics) such as those of us around here, there are very tightly held - not to mention very diverse -opinions of "What is exactly right!". Look at other discussions as people are working on their Mustangs.... "Getting rid of Ford's cheap xxxxxxxxxx!" "Why did they do that???" etc, etc, etc. Your original-design drop spindles met one of those first needs.
When the idea of making them "drum-type" spindles came up; "cries of joy!" as they would accomodate so many different brake designs that were already adapted to the drum spindle. This was important; because there are so many diverse designs, and so many diverse "backers" of each design. "FRE's disk-conversion is better than Acme's!" "Yeah, but the Thunder-chicken big brakes are great, even better if you use Chevro-mob-lac calipers!" You were serving a here it comes again) diverse market. You actually had even me initially, because I couldn't find any entity that had a solution for my factory disc spindles to go to larger brakes. The only thing that at first caused me to balk was the "drop" - I wasn't so sure that I wanted to lower my Coug. Plans change, I'm a convert.
If you think this is bad; you should live in my world; with two other competitors in the "Internet Broadband" market. We're less expensive (by half)than both; but
1.)The speed numbers on our price-leader product are "lower' than the cable company (that's deceptive because of the different delivery configurations, but subject of another discussion)
2.) You have to plug our modems into a phone jack. No the TV cable won't work (wrong company); and they don't pull the internet out of thin air (the third company).
Still I end up taking "It won't work! (because I don't have a phone jack near my computer)" calls; as well as "It's too slow! (Because, at 3AM on a Tuesday with everybody else in bed, the cable modem gives me real 3Mb/second on "Bob's Broadband Speed Test Page"; whereas your cheap-a$$ product only gives me 1.5!)"
"Yes, but ours does 1.5 all day, regardless of what time it is or who else is on!" The fact that we sell 7Mb service as well, doesn't come into play; because "It costs almost as much as a cable-modem!"
Diversity - ain't it a wonderful thing? Everybody has their own opinions about what is right; and you know what they say about opinions - even yours and mine.
2) Most users express the desire to use performance calipers/rotor sets with the spindle. This is a very important concern. By far, the current choice for performance is the Ford 13" rotor using the PBR aluminum sliding caliper commonly used on SN95 Cobra, Mach, and Bullitt.
I have address the 3 design/product goals. The spindle will have a 1.5" "drop". The spindle will directly mount a KH 4 piston caliper, will directly mount a GT SN95 PBR caliper/bracket (no intermediate bracket parts), and will accept my version of a bracket to allow the mounting of the "Cobra" caliper/bracket. I will produce a rotor (probably with a reinforced cast in hub) that will bring the caliper and rotor disc surface 1-2" closer to the car midline, as compared to the 2 leading competitor brackets.
To my knowledge they are the same caliper with a different esthetic treatment. They use the same pads and rotors if I'm not mistaken.
Any updates?
My 65-66 KH based kit parts are on route now. I just need to find a source for the bolts that hold the caliper onto the caliper bracket. They are called stripper or shoulder bolts. The shoulder, the part of the bolt shaft that has no threads on it, is larger diameter than the threads. They are sold by SSBC, but I can't rely on them for a critical part.

Thanks Jim, I'll check with them, although I fear that even if they quote, their bulk price will be more than the SSBC retail price ($3 ea). I usually seek to get very basic (close to the source) with my kit parts. I know who made them originally (Rockford Screw Products) . Their incarnate claims they can't/don't make them now. The ones sold by SSBC are an exact reproduction, right down to the brandmark. I'll eventually find a source.Check with Fastenall or McMaster-carr for the shoulder bolts. I've spec'd shoulder bolts out before on some oil rig designs and they are great...

Thanks, I suspect they are the source for SSBC or vice versa. They do provide an original part number. Now I must wait till Monday to talk to them.
Degins,
It seems that the interest for a drop '70 drum spindle does not meet your marketing plans but why not a drop '70 disk spindle (i.e. Granada)? The Granada brakes you currently sell would work and SN95 brakes would work with the bracket you recently designed for Granada spindles.
