Anyone here know lots about MGB's?
I do some kit building for other people, and one of the jobs I have on at the moment is the completion of an NG TC.
It's based on MGB components, and basically I am working with a rolling chassis and various boxes of various bits.
Long ago I dismantled an MGB but I've forgotten a lot of what I learned int he process (except how heavy the front subframe is!).
A question I have at the moment concerns the remote brake servo, and how it should be plumbed in. A normal brake servo operates on the pushrod so
effects both parts of a tandem circuit, but what happens with a remote servo? I don't have an MGB handy for studying so if anyone here knows I
would be grateful (I might have some other questions later!)

Your MGB donor had the standard UK market set up a single circuit Lockheed master cylinder with remote servo ?
The MGB remote servo was single circuit end of story, if you convert to dual circuit and have and still want to use a remote servo you either two
servos or an expensive double ended servo.
You could of course fit the US market MGB dual circuit tandem master cylinder setup without servo.
If you are using an MGB pedal box you also could of couse fit a Triumph Spitfire 1600 dual circuit master cylinder it will fit straight on and is
designed for use without a servo.

The guy who built the rolling chassis had plumbed in a non-servo single circuit master cylinder (this was a pre SVA build), although as there was no
pedal box fitted I can't see how he intended to set it up.
There does seem to be an MGB master cylinder with forward facing direct servo, not sure what these come off but it might be a good idea to get one.
Any idea which car this comes from (it's supposed to be an MGB unit).

The master cylinder/servo in your picture conmes from a 1977 onwards MGB - rubber bumper model. I have fitted one to my 72 roadster, they appear on
ebay quite often, some folk take the pi$$ with prices, quoting things like:
Rare.
Essential for v8 conversions etc.....
I think I paid £20 for mine, and about £10 for the rebuild kit.

I don't know how much work you expect to do on the car or if you want to spend the money on some books that i have from an MGB restoration
project i did some many years ago.
I have Haynes MGB 1962 to 1980.
Haynes Guide to Purchase & Restoration of the MGB ( Lindsay Porter).
Moss parts catalogue, this has a Schematic of every single part plus numbers, very usefull.
Moss Perfomance Manual, all the upgrades and part numbers.
Looking for £50 posted, 2 inches thick and quite heavy.
If there of any use to you.
