NEEDED BADLY! 7 1/4 diff section and pinion gear

Ok so mine grenaded and is completely toast. I was going to switch to my 8 3/4 but I didn't realize that I also had to swap brakes and such IF I can find them.

So, I'm in need an a 7 1/4 center section so I can at least keep my Dart on the road.

I will also need a replacement pinion gear as well.

I need one ASAP.

On a 7 1/4 there isn't a drop out center section. It would be easier and cheaper to find a complete rearend.
