I don't have any pictures of when I did mine, but its pretty self explanitory once you get the front covers off of both engines, there are 3 holes that mount the crank sensor mount to the block on the early DIS engine, two threaded and one dowel pin, they are 6mm threads and a 6mm dowel pin, you probably won't find one though, what I did was take a 6mm bolt with a long shank and cut it off so the shank was about the length of the dowel in the original engine and just threaded the hole and red loctited it in place.
to make your template, get a piece of thin cardboard like from a cereal box or something, cut it out in a relative shape to fit in the area needed, you want to use the outer bolt holes for the cover for reference points so make it big enough to get to those. Start with the hole for the pin, cut it out in the cardboard first, then take a STRONG pin or something and stab it into the holes you want to use for reference one at a time, after you stab the hole in the cardboard cut out the excess so that the correct bolt will fit through then put it back on the engine with the bolt threaded in the hole, this will help in accuracy, Start this process with the outer most cover bolt holes (I would do 3 of the cover holes for good measure, you don't have to do all of them) and then do the other two holes that need to be drilled and tapped. when you get to the new engine, take a scribe or something to scratch the metal or a sharpie and mark the holes that need to be drilled and tapped, take a center punch and mark the center as close as you can, then drill a small pilot hole like 1/16" or something then drill the correct size hole for the tap ( I believe it's 3/16" for a 6mm). at least one of the holes goes all the way through to the crank case so you will want to be careful, with the front cover off you can catch all of the chips without a problem just use some loctite or thread sealant on the bolts when you put it on. That should cover that part.
you have to use the crank pulley from your '91 engine, it'll swap right over. Once you get the sensor mounted and the crank pulley in place check the crank sensor alignment, take the pulley part of the pulley off (4 bolts with 10mm heads) and rotate the engine, there are some points where you can see both vanes entering the sensor, just make sure they are close to centered, when I used this method I didn't have to align the sensor after the swap it started right up, but it doesn't hurt to check.
