Started a MM & OPG yesterday and decided to keep an eye on the clock to see how long it really takes.
From parking the car on my ramps, removing the front wheels to laying the cross member on the ground next to the car took 3 hrs and 45 mins.
Leisurely pace and stopped twice for a cup of tea. Used an air wrench.
Next step this morning was to remove the OP. Took about 1 hour and 5 mins.
The majority of the bolts take 5 mins and the last 4 took up the rest of the time.
Going back now to clean up the OP and install the OPG.

Now I know that replacing it is not too big a deal, I would be much less concerned about removing it. However, I'm in no hurry to replace the OPG...

Paul,
Came up for a cup of tea.
Not trying to prove anything here just wanted to time the other process instead of guessing it.
I dropped the crossmember on my head - that did hurt. You would think I would learn after doing so many!!!!!!!!!!!!!!
I have a ton of pics I will post some of them later in case it is useful to someone.

some people paint them with one of those paints that you can use to paint over rust; do you think this is a good idea?

4 hours to button everything up and torque everything down. Fill up with oil and start her up.
That included removing the cross member a second time as I forgot the large plates on the bottom of the MM.
About 11 hours steady work.

Roger - I just received a $1240 labor estimate for oil pan gasket and motor mounts (no parts - labor only!). On a scale of 1 to 10, 10 being hardest -- leave it to the pro's - how would you rate the MM/OPG job for the DIY'er? Recommended or stay away? Mike

Mike, I'm not Roger, but I know the job fairly well having done 3-ish myself. The answer is about a 5 on the DIY scale. Nothing in the job is particularly difficult, but it's very dirty and without air tools it'll be long and disgusting. For that money, if it were me, I would go ahead and buy the parts and whatever special tools you don't have and do it.
Besides, teh shop will find a way to goof it up, and then you'll have to clean up the mess they made.
The job requires a set of 3/8 drive sockets, ratchet, extensions, some pry bars, a 10mm gear wrench, and a few screwdrivers and pliers. Nothing spactacular about the job, but it is very messy. A hammer and punch would be nice for the tie rods and the upper crossmember bolts but it can be done without that.

For that money you could get a tie rod separator, an engine support, a floor jack & stands, an air compressor, an inexpensive 1/2" air gun and a 3/8" air ratchet, and a nice torque wrench. In fact, you could probably get all those for half that estimate.
Having done the job(plus the rack) myself, it was probably 24-ish hours, but that includes lots of fiddling with the rack, tie rod ends, etc and thoroughly cleaning everything and stopping to admire stuff here and there. Throw in a parts washer or steam cleaner(total still under the estimate you have) and you could probably do the job in ~12-15 hours determined effort.

DIY is the way to go - if I can do it anyone can.
PM me and I will give you my phone number and I can talk you through any issues you may come accross.
I can also supply the MMs and OPG if you need them.

Otherwise, your time estimates are right on. My first time, working alone, took me 13 hours including some down time.

Bill,
I used a long blade screwdriver to apply some pressure on the head from below while using the gearwrench which helped a bit.
Not a lot of room in there.

What you need is one of these "Gear Wrenches" - they don't have gears just work on friction. Best tools I ever bought
