After the transmission...

Well, actually, before the transimission...here is a copy of the Record for A/SA that we won in Las Vegas..

That was for all of those out there ,who have never seen one, and don't own one.

Now, back to the car. What comes after the transmission? The drive shaft. But ours is nothing special.

When we got the transmission, the rear end was already in the car. So to connect the two, we needed a  drive shaft. So we called Mike P, and said "Help!!!"  Mike told us how to measure for the drive shaft, and we measured it about 11 times, each time wondering if we had gotten it right. So then, we pretty much just averaged the numbers. And that is how long our drive shaft is!

But next to the rear end, or differential. Once again, conventional wisdom said Dana 60. Tough as nails, and downright bulletproof.

But by now, we were pretty sure that bulletproof wasn't necessary at the cost, in terms of dollars, and weight, and inconvenience of the Dana 60.  So once again, we go against conventional wisdom, and instead of the Dana 60, we went for a Mopar 8 3/4" rear end.

And so far, we have not regretted that decision one bit.

The 8 3/4 is a Moser aftermarket assembly approved by the NHRA, and yes, there is one small issue that exists with it, rather than the Dana 60.

The rear end ratios available for the 8 3/4  is not as broad as for the Dana 60. For example, the steepest gear we have found so far for the 8 3/4 is 4.86 while there is a 4.88, and even a 5.00 available.

I know of at least one other Drag Pak that has run the 5.00, but it isn't necessary for us, because we already have a better 60 ft time than most other Drag Paks..

And, on the same note, changing a rear end ratio on a 8 3/4 is much easier than a Dana 60. So, if we ever need to change it, we can change it quickly.

God Bless, and Race Safely
