MG MGB GT V8 Factory Originals Technical - Pistons needed for Princess twinpot calipers

Having gone the Princess Caliper and Peugeot Disc route to upgrade the brakes on my conversion ( not yet finished but moving forward!!) I got the spacers and new pistons etc. from Godspeed Brakes in Wales. When I came to fit the pistons (about 10 months after purchasing) the chrome on the ends was peeling. I sent them back after great difficulty in making contact, and many ignored mails later have been told they were returned to me 5 months ago - but never arrived. Now I can't get any posting details from Godspeed.
So....
1. Don't buy anything from Godspeed
2. can anyone tell me where to buy some from
3. Has anyone got the dimensions and tolerances so I can get some stainless ones made?
4. If so what grade of stainless is recommended.
Thanks for your help

Pete,
My calipers are in bits at the moment. I'm happy to measure the pistons (which are in good condition) with a micrometer.
If it turns out that they are not generally available, it would be interesting to see if others were also in the market for stainless pistons. It may be cost effective to get a job lot machined? I'm not home until the weekend....if you contact me off-line by email, I'll give you my phone number.

Thanks for the info so far. I have the original pistons so can measure them thanks Pete. I would like the official dimensions if the design info is available somewhere.
I will give Dave Vale etc a call.

Pete,

A friend of mine manufatured exact copies of the Princess pistons on a manual lathe. They were made out of top quality stainless steel. Works fine.

Hi my mate had problems with Godspeed were he sent money off in the form of a bankers draft, as he was told that the credit card processing was down.
This was 4 years ago and he never did receive the brakes.
He was awarded the money (£590)through the small claims courts but the guy never paid it as he just declared himself bankrupt and reopened the business in his wifes name!!
I have read a lot and I mean a lot of bad comments about this guy on other forums.
So buyers please beware....
