Never dealt with a triple, but generally the engine is angled slightly clockwise, like if you loosened all but the farthest engine mount and pushed forward on the primary clutch. The engine side of the secondary should be out from the alignment tool by around .040 with the far side touching. So it's not much of an angle. The secondary usually has a few washers on the bearing side, I think 1"ID x 1-1/4"OD, which are available in two or three different thicknesses. Then there should be a solid bushing the bolt goes through plus a stack of flat washers and a big end washer; as you add the washers on the bearing side, you also add to the outside to keep .030-.060 freeplay. The XLT is a Wedge chassis; was the engine from a different chassis? You might want to go shopping for a different engine plate, could be you just need one for a Wedge with a standard (non-monoblock) triple. Not sure on that, but while you can make just about anything work in these, it could be a lot of unnecessary work.
