I wanted to buy and install one of those covers that are supposed to strengthen the 10 bolt and look great at the same time.

But after reading many of the threads on here and on some other websites, there is mention about having to machine oil passages on the cover/rear axle so that oil can flow to the axles themselves for additional cooling? So it's not install the cover and be done with it?

Never heard of that and dont see why you need to cool the axle shafts...

I got the info from here:

i just put one on and didn't have to modify it

When I had a 10 bolt, I just bolted the cover on. No requirement for modification. Oil will always go down the tubes to lubricate the end bearings. The ring and pinion splash enough oil around to coat everything.

I've never heard of anyone doing anything like that.

I mention the oil passages from the website on the third thread above. I was looking at his site for the 1LE brake conversion and then came across that bit of info. Not sure if it was specific to the cover from AAM.

Didn't have to do anything like that with my T/A performance cover back when I had a 10 bolt.

no issues/mods with the moser cover either.

did you read this thread you posted? The cover in question has some kind of cooler thing built into it and the grinding is to create a path for the oil to get back out of this cooler thing. Sounds pointless and probably edplains why nobody has ever head of this

Of course I read my own post as I wrote it.

I should have been more clear as to say if "all aftermarket"/ non-stock rear end covers, regardless of them having a built in cooler or not, would need some sort of modification. This would be my first install of a rear end cover and wanted to make sure it was just install, refill oil, and drive away.

The 7.5 rear end usually takes right about 2 quarts of oil. Most of the after market covers will hold a little more oil, so buy extra oil. Never use the hole in the after market cover for the fill line. You should always remove the original plug in the housing and use that for the full level.

Here's what I put on mine.

The cover is 1 inch thick High tensile aluminum alloy and also made in the U.S.A.

Keep in mind also, that the page on Dan's site that you linked to, is near 20 yrs old now, and AFAIK hasn't been updated since probably 2000 or so. Who knows what parts it talks about are even still available, or if they're the same now as back then, or what.

I do recall that there were covers available back in the day had a sort of fluid cooler passage cast into them. Not sure which ones though. I know my T/A one (looks EXACTLY like the LPW Ron put up pics of) does not. Virtually all of them on the market look exactly like that: almost like everybody buys them from the Acme Cover Casting Co. and just has a different nameplate put in to "private label" em. No idea whether that's true or not, just, looks like it.

I would also add to Big's comments about using the aftermarket cover's fill plug: you can use it to fill through, as it's MUCH more convenient sometimes than the OE plug; but even when using it you should always take out the OE plug and fill it to that level ONLY and not all the way up to the one in the cover. If you fill it to the level of the cover plug you'll be putting in enough fluid that the axle tubes will be half full as well as the pumpkin, and the axle seals will leak ruthlessly.
