Several ways to do it but, I am going to install engine and transmission, set the car at ride height, measure then place on jackstands or ramps. The rear is bolted in snuggly but to where a deadblow hammer will still allow adjustment. Take transmission yoke angle then pinion set to angle needed and tack weld the perches. After that I will finish the welds. You shouldnt set pinion angle till you know what your transmission yoke angle will be @ more or less your ride height.
This is the step I'm at on my 68.

Since I'm using the same spring and the same torsion bars the ride height shouldn't change. Does this mean I can just use the same piinoin angle of the 7.25?
 
You can try it that way, myself you see how im going to do it. Granted I dont have the original 9" for mine to go off of and am adding a TKO600 in place of the toploader, but on the 67 I will do the same process even though I have the same tranny and rear to go off of. More than one way to skin the proverbial cat.

It's all about how much the pinion is going to climb. Mushy factory springs may need more angle than ss springs. But here's what you want while you're cruising down the road. I'm sure there's lots of math formulas you can use and get all frustrated but don't sweat it to much. If you screw it up you can throw a wedge shim in it, lol.

That makes since. I do plan on using ss springs later on. I can afford them yet but that is in the works. I actually have a set of them wedges because years ago when I installed my shackles I was told that I would have to adjust the pinion angle to accommodate for the lift of the shackles but I never did it did fine without them. Yes I know shackles are dumb I was 16 it I thought it was cool at the time! I cant believe they allow 16 year olds to drive we are really terrible decision makers at that age! Haha

Never did shackles. Bald N50s and air shocks, you bet!
Back in the 80s shims were included in truck lift kits. Might still.

I always wanted air shocks too but never could afford them Haha. Shackles were cheap now I regret it and wish I had the original ones. The original style shackles are not cheap now! They are like 70 bucks. That's crazy for 4 pieces of flat stock and 4 bolts with rubber bushings around them! I will probably just use the shackles I have now and put them on the lowest adjustable hole and cut off the extra until I can afford better.

That's exactly what I did man. I ain't paying for repop Mopar shackles, either. Haha. Not for a beater hotrod. Look at the before pictures of my car you can see it had long shackles. Chop saw fixed 'em.

My cover has a rubber drain plug in it. It is leaking and I can not find this plug anywhere.
