So three or four questions: How do people grab hold of that nylon washer to pull the M5x0.8 bolt in the simplex lever? It seems too deep for a needle nose to grab. Should I jam something like a toothpick along the side to pin the nylon washer while I turn the screw?
As [MENTION=172094]Chombi[/MENTION] mentioned above ^ The plastic washer just keeps the mounting screws from falling out when the levers are not mounted. I just push the screws out with a punch or what ever fits in the hole. I don't bother putting them back in.
Some of the first generation Simplex Retrofriction levers had a metal spring washer holding the screws in. They were hard to remove.
Most French Simplex shift levers were mounted using "bātard" 5mm x 1.0mm screws. The industry standard in 5mm x 0.8mm (Campy used 5mm x 32 tpi which is almost identical to 5mm x 0.8mm)
I've replaced the Simplex screws with industry standard 5mm x 0.8mm stainless steel socket head screws on Retrofriction Levers.

I bought several NOS Huret clamps on eBay (beware, they were made in 1" diameter for Schwinns as well as the standard 28mm - 1 1/8" diameter).
The clamps on earlier Huret levers that used proprietary cables with 'banjo" ends may wont work with anything but Huret levers (never tried them but...). Jubilee levers too...
The later style levers that used standard style cables with "barrel" ends are the ones that I've checked and the will work.

Third question: will grinding the huret band with a dremel improve how it mates with the simplex lever (inbred lineage be damned)?
Simplex Retrofriction levers have a square on the rear that fits over the squares on clamp bands and brazed on lever bosses.
You may have to grind or file a little off of the corners of the squares on the clamps. See arrows on the picture below.

I can paw through parts at a local bike kitchen and possibly find one of these clamps. Thanks all!
Earlier Campagnolo clamps have travel stops and cable guides which are pressed on. They wont work without destructive modification. Later levers with removable stops may work... I don't know...
