olememphis, I do not have the perch block part # listed but Joe Wiemer "2many2count" gave me that tip. I know he has the part #. I had a friend of mine who delivers parts for Dodge to pick mind up. Cost was less than 10 bucks for the pair. Yes, they will work good. I liked them because they had 3 holes in the bottom of them and I was trying to center up the wheels in the fenders on my panel. The holes in the bottom let me move the rear end forward about 1 1/2 inch....or backwards, and still sit on the springs center bolt.
I'd recommend changing the pumpkin first and then setting the pinion angle...then getting your drive shaft cut to length. If you want to know how to measure for the drive shaft let me know. I have a sheet I can seed you.... if you want, send me an email and we can chat a bit on the phone. If you have verizon its free anytime as I am on it....or I'll call you after 9pm my time at night..... or free anytime on the weekend.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
