He is, or was, originally a 914 guy.
More recently he has moved into vintage 911 stuff.
Always have been, always will be -- "both". My first Porsche was a 914 though.
I currently own two 914's and a 911 (plus an SUV and school bus sized truck thingy). We're currently restoring 2 914's and a 911 for clients. I'm good with that ratio. I haven't really "moved" anywhere, I'm just too busy to play here that often.
We currently have a mixture of Ferrari, Lamborghini, Alfa, F3 (those are really cool), Lancia, 908 (wow, I'll have to post some amazing pics of these), 911 and of course a bunch of 914 jobs in-house... including about 8 pair of 914-6 and -6/GT calipers for some reason.
The most important part of a DIY caliper rebuild is the zinc plating. ATE chose zinc (not cad) 40+ years ago for it's superior anti-corrosive properties. It's actually a sacrificial coating and the fact that we have calipers to rebuild today speaks to it's absolute coolnessness.
If you can't find a local plater, we can do it for you for $60.00 for the pair. This can be beneficial as most platers have a "Minimum Batch Charge" that's usually about double that.
The bores need to be plated. Without that, the caliper will begin to exhibit the same issues it has now, in a year or two. 99.9% of all caliper failures can be attributed to rust -- "inside the bore". Resolve that issue and perform annual fluid changes and you will never have to rebuild your brakes again in your lifetime. Most re-man caliper are baked then tumbled in steel rods and coated in oil to keep them from rusting just long enough for you to get them on your car. They are unrecognizable in a couple of months and, if left to the elements much longer than that, they are metal scrap.
There's a video on YouTube for the rears and a lengthy tutorial on the site for the fronts.
Good luck.
