I've just been onto the original suppliers of the inlet manifolds and asked about the possibility of them supplying another set or even to make a small run of them. As their response was not enthusiastic about re-manufacturing these I shall not hold my breath. It would seem that most of the original staff that were involved in the original business have left and since they moved to their new premises, in the last few years, many of the old tooling/jigs have been discarded.
I shall hold out for a few more weeks before even contemplating making the inlet manifolds. anybody interested in the quad DCOE inlet manifolds fabricated in steel please send me a PM as that will help with an idea of numbers that might be possibly interested in them should the OE supplier come up trumps.
I have attached an image so that everybody is aware of the manifolds that I mean.
