A quick update for you all.
This is how the P100 looks at the moment






Also I have just received a prototype diff bush for the Sierra (the P100 has all the rear modified for a cosworth back axle) so here is a few pics as a taster for you all



Sorry about the grainy pics of the mount but used my mrs mobile which isn't as good as mine for pics.

I am hoping that it will be possible to replace the bush on its own instead of the whole mount should this ever fail but only time will tell.
It fits great and is really solid so will be a great improvement on the standard crap rubber mount. Well impressed
