<VV> drain plug question

[Bryan Blackwell]

Hi Randy,

Yes, you sure can.  I did one, be aware that the case is really thick right there, you'll be drilling for a while.  I did mine with a smaller plug for that reason - 1/8" NPT as I recall.  Should still drain just fine.

But I noticed that the '65 diff just has a boss cast in the case (no drain plug), whereas the '61 diff has a drain plug drilled and tapped and installed.  Since I have everything apart at this juncture, is the '65 diff case made the same as the '61 case?  If so, that means I can go ahead and drill and tap it and install a drain plug in it,  with no issues, right?
