Well, if you want to fix the wiper park problem I think you're going to have to open it back up at some point. If you're waiting for someone to chime in and say they've had the very same problem then perhaps don't hold your breath unless it's someone like you or me who's taken the assembly apart and not tightened that nut enough or had the motor gearcase wear out. If you need more proof then you can always wait until your wipers are faced with a snow load or the blades are frozen to the glass or you go through a brutal car wash and the park position will likely move again.
I have not really heard of 740/940 wiper motor gearcase issues such as might cause your problem, mostly just worn out, dead, intermittent and slow motors. I said your gearcase cover was likely riveted in place like my 940, but checking catalogue pics of the 740 ones shows there are screws, leastwise in the remans, which are available from a number of on-line suppliers if you get desperate. If after a realignment the park position slips again then consider opening up the gearcase for an inspection of the gears and electrical contact points, although the odds of being able to fix something inside are slim. I mentioned replacing the whole wiper assembly only because that might be fastest and easiest at a pick-n-pull, but you would only need the motor and it could save you a few bucks. If you don't have suitable 740 donor cars in local yards then also look at 940s. The only difference I can visually spot in catalogues is that earlier ones like yours may have two 2-pin electrical connectors whereas the 940s use a single 4-pin connector (hack them off and splice in the old ones if needed).
Yes, I get your reluctance to open it back up again. It's of course not that hard, just a bit tedious and not a 5 minute job. I forgot to re-install the rubber grommet in the plastic motor cover, not at all critical. It's still sitting on my work bench waiting for me to have nothing better to do but open it all up to put it in, so like you not in any hurry. Odds are I'll never need to open it up any time soon, so some day I'll break down and do it just to get the part off my bench. Biggest wiper problem I'm having at the moment is a missing plastic nut cover on the tailgate wiper arm somehow broken in a parking lot or car wash. A 50 cent part no longer available, but the yard says I've got to buy the whole wiper arm from them, not cheap and it's specific to 940 wagons -next time I'm in buying parts we'll see if I can negotiate the price down a bit.
Again, good luck.
