I am into a real nasty tight situation with steering universal joint clearance on my roadster pickup build. The intermediate shaft which runs between the universal joint on my Vega box and the universal joint on the end of my steering column will clear the exhaust pipe and manifold if it runs straight back from the box, however when it is swung up to mate up with the end of the steering column shaft it interferes with the exhaust pipe. I believe that if I am able to make or buy an extension peice for the Vega input shaft that will extend it about 4 or 5" before the universal joint, then my intermediate shaft can swing up to mate with the column universal and be clear of all obstructions. I don't want to buy headers. I see that Borgeson sells an "anti-vibration" coupler that is 1 3/4" diameter x 3 1/2" long with a female spline on one end and a male spline on the other, and that they also sell splined couplers and adapters. I am running a small block chev engine and rams horn exhaust manifolds in a model A chassis and body.----Has anyone out there encountered this problem, and used some method of extending the vega input shaft to resolve it?
