I'm trying to get my exhaust to fit, and using the build manual for the convertible, since it's the only one I have access to, but I'd imagine the instructions for the coupe would be similar.
I've made three brackets - MM09, MM10, MM11 - as detailed in the drawings section, and now I'm trying to get them to fit with a new SS exhaust from Alistair.
First question: the rubber bobbins mentioned. The bobbins I've managed to get have a rubber depth of 19mm (that's the total length including the steel washers bonded to them). Should I be using the deeper type, as used to support the rear of the gearchange? If not, and I'm using the correct sort, then I presume the exhaust must get bolted to MM11 (the flat plate with a bend in it) before MM11 gets attached to the bobbins.
Next question: is the exhaust as supplied by Alistair to the same specification as the original Midas exhaust? MM09 (short length of 25mm x 3mm with a twist at one end) doesn't seem to be anywhere near where it needs to be to attach to the "front" end of the back box, given that I can only find one 8mm hole in the spare wheel well. I can always make another bracket, but I'd like to mount the system the same way as the original, if possible.
Finally, MM10 (a "U" shape with one short leg, which supports the tailpipe) - using a 19mm deep bobbin, there is very little clearance between the body and the top of the tailpipe - a few millimetres.
Finally, what clearance should there be between the fuel tank and the exhaust? I'm looking at somewhere in the region of 5mm, which really doesn't seem very much. I don't know what temperature I can expect that part of the exhaust to be, but I'm concerned about such a small distance between the tank and the exhaust.
