Wiring harness for an MGB fitting a Rover V8, help?

Hi All,

As you know I'm building an MGB GT V8 and I have a dilemma regarding the wiring loom/harness.

My donor car is a 1971 model, and the new shell i'm rebuilding is a rubber bumper (77) shell. The main difference here except the obvious is that the later car uses the combined brake servo/master cylinder instead of a remote servo.

Where my problem lies is regarding a new loom. The car is being rebuilt to look like the 1971 model with the same dash etc (steel). BUT on the earlier car the fusebox and relay connections are located where the master cylinder is on the later shell. Now I could get a later loom that has these connections further forward and out of the way of the cylinder, but then i'm not sure if this loom is rubber bumper only and I will have a steel dash.

My other option is to buy a 71 loom and just join and extend the fusebox wires further down the engine bay. Whats best?

Can you not ask the maker of the loom or the MGOC?

Unless they answer the question, personally I would get a '71 loom and extend it. I would have thought you could do it neatly too.

Your going to use a 40 year old loom ? I'd get one of the many kits and adapt it to suit

Thanks Richard that's what I'm going to do.

Nope I'm buying a brand new loom, but when I refer to years its the model year not the age of the loom I'm using.

I'd have thought your 'problem' is unlikely to be unique? Nobody make a loom to suit?
The new loom is almost certainly new rather than NOS, and it wouldn't be much different to make a custom one which is a mixture of the two if you are already geared up to make both.
