Is there reasonable working room to replace the T-5 tailshaft seal while the H-Pipe (& exhaust gas recirc piping) is still in place? I currently have the driveshaft unbolted from the pinion flange. I have the driveshaft's rear half supported by a piece of 4" wide plywood that bridges the two Flowmaster chambers. To provide clearance of the driveshaft yoke to the tranny, I figure I can slide the driveshaft rearward until it hits the top of the differential. However, the cross-pipe in the H-pipe may inhibit working clearance for removal & installation of the seal. Any thoughts & suggestions on the working clearance needed (H-Pipe in or out) to do a removal & installation of the seal? Am I making it unneccessarily hard on myself by leaving the H-Pipe in during the job? CAR: 1987 Ford 5.0, high miles, original T-5, original factory H-Pipe & EGR. Thanks.
