Chris, I hear what you're saying, but it sounds expensive. I wouldn't know where to begin in fabricating a support. Some of us run Supras on a budget, although I'm rapidly coming to the realisation (having had two Supras suck every penny) that running a Supra on a budget is a contradiction in terms...
(I had a service at ToyotaGT yesterday, and the list of things they told me I need to fix - including the manifold - is as long as you're arm!)
