Bob Helt, it was a 'typo' on my part.  GL-4 is correct.  I try to help 
and I only make matters worse!

I have to ploofread more carfully.

Here's the original message, corrected:

Richard Widman's writings helped me immensely, and my local club tackled 
this issue for a tech session last Fall.  For the tech session we had on 
hand a Brad Penn product, an 80W-90 GL-4 specifically recommended by 
Brad Penn for older transmissions and hypoid gear rear axles.

Everything I have read to date leads me to believe that this particular 
Brad Penn product is the right one to use.  There are others, but I was 
able to order the Brad Penn product from Amazon, where a case of 12 
quarts cost me $82 delivered to my door.   This stuff is now in my 
Rampside (as is Brad Penn motor oil).  Aside from Amazon, there are some 
Brad Penn dealers around, so depending on where you are you may be able 
to pick up this product locally.
