i just looked through the ss parts catalogues i have-my 76 switch and 75 ss switch have different part numbers-76 was mounted in dash-75 mounted on frame in front of left side cover.
i think different numbers related to number of connections-76---6 way,75--3 way----the rubber boot for both switches have the same number-suggesting they are the same size.
my 860 gt had the switch mounted at front left under tank on a bracket.
hole size unknown-i sold it 32 years ago.
my switch is 22mm-and yours?-perhaps nos was for 860 or it was--nos: not old stock
i presume you are trying to mount switch at rear of tank
what size is the hole

oz s

The hole at rear of tank is approx. 21.5 mm, definitely smaller than the switch.

wdietz, I would love to see a pic of that Ducati key if you could post.

Cafe, My camera is at present vacationing in Fla.When it returns tanned and fit I'll try to post a pic. Bill

Bill, how was the FL vacation? Still hoping to see a pic of your key. Jordan

Jordan, The camera isn't speaking so I assume it had a good time.I was here in Maryland the whole time trying to make a living.I'll try to get the camera out of its stupor and shoot the key.I threatened before to shoot some pix of my old 900 racer and post them. Hopefull I can do it this weekend. Bill
