Sounds like Calvert sent you the Monos that are the same length as SS springs. He makes them both lengths. Put the hangers that you used with the SS springs back on. Problem solved.

In theory, there is no difference between theory and practice. In practice, there is.

Not a great deal to worry about imo.
I would lengthen my hangars and put the axle in the position it was.
Either lengthen the short hangar or get longer ones.
I have a pair of F body ss hangars that are really long.
just a matter of drilling the spring eye holes where you want.
Possible to weld a 3 inch pc of plate on the hanger and redrill new location?
some pics would help.
Ideally if you have NO issues, that 1 and a half inches would be ideal as it ultimatly puts more wght on the real axle.
I personallly dont like locating on anything but the center of the spring.
for your info, there are products available that adjust that dimension so I cant say it wont be ok, I just dont care to set up suspension that way.
unfamiliar with b body hangars and there configuration.

Here is the deal if the locating pin is in a different spot than you do not have the same mesurement of front segment. You measure the front and rear segments by pin location. I don't know where you are measuring from. Sounds like you have the wrong stuff. Somewhere someone measured wrong. I have put on tons of these set ups and never ran into that. Jake

Cape , I have my rearend pushed back 1 1/2 inches , all you have to do is remove the center bolt , slide the spring back and drill another hole for the center bolt.

Length of the front segment does not effect the shackle angle , but I did have a problem with the shackle ( 20 degrees ) , you can get the proper angle in two ways . Put a new mounting hole in your frame or adjust the rear segment of your spring to get the angle you want and then drill another hole in your rear spring where you want it to be.
I now have 37 degree angle on my rear shackle

This is the weird part travis at caltracs gave me measurments to check out and everything is perfect he told me the rear shackle when there is weight on the suspension should be at the 6 oclock position and mine is. Its just strange to me to put the spring pad on the front hole. will it effect my pinion angle? Thanks for all the info
Shouldnt effect the pinion angle... its mounting to
a flat plate per say... but as always... check it

My car is a 69 charger Hemi 4 speed. I had bad luck last time out at the track. But switched my superstock springs out for the caltracs and mono leafs and shocks. Has anyone used these springs on there b body cars? Cuz when I put mine on and set the rear end on the dowl pin it moved my tires forward 1 1/2" and the tires were touching the wheel well. I called caltracs and all parts were right on no wrong parts sent. I have a strange 60 Dana in it and on the spring pad where u set it on the leaf springs the Dana has two holes when I had it all together I had it on the second one which would be center and it didn't work so I put it on the front one and it centered everything up. So now I have to get longer caltrac adjusting bars. So I was just wondering has anyone else had this problem? Oh ya the front hanger for the springs are stock which is what caltrac people said they have to have. Will putting the Dana on the front hole on the spring pad affect anything pinion angle? Thanks
I think you are measuring from the pin to the front
eye and being that your pin is moved forward you
can use the A body spring with the standard hanger
but if you move the pin back to the axle centerline
you would need the B body spring... thats just the
drift I'm catching here

I tried the ss spring front hanger with the mono springs and it didnt work I have the right ones that measure 22 not 20 i have no idea what the problem is all I know is that the only way it all works is to have the dowl on the spring go on the front hole of the spring pad on the dana.
I'm wondering if THATS not how it was set up BEFORE you took it apart. I mean, are you sure it was in the center hole to begin with? Not suggesting you're a dummie, but with cars changing hands over the years and diff stuff being swapped out it wouldnt be the first time you didnt have what you thought. People will do this to accomodate diff driveshaft lengths. Look at your old springs and see if there is an outline of where the perches were sitting and just see if they were centered before. Just a thought, cant imagine how it would be so far off. 
As for pinion angle, it may affect it a small amount, but, going from a heavily arched spring (like the ss) to the much flatter mono can change it quite a bit anyway. Can you get sideview pix with the SS and the mono to put up here? That may help to see it. One thing that can come into play here is a lot of times going from a ss to a mono will lower the body which will bring the tire closer to the wheel lip. The wheel on my Dad's Volare looked centered til we did the Clavert deal, which lowered it quite a bit and brought the tire much closer to the lip. Same deal on my buddies 68 Cuda. Had to trim the lip a bit for clearance.

the only thing im worried about is pinion angle and will the u bolts be under any added stress that they will snap. Thanks
If they are the factory bolts that kinda flatten out in the area around the axle tube, with a 4 speed I'd replace them with the ones that keep the same dia all the way around, like those in the pic. As someone mentioned earlier though, you definately need to box in the back half of the perch especially on a 4 speed car or you WILL bend them. My Dad's car had this happen and it is only an 11 sec auto trans car.
Here is how mine were.
