Ok, I found a place near where I live (Betts Spring Co.) who will make the springs I want for $95-105 (wahoo!). I was thinking about making springs very similar to the Hotchkis (the longer bottom leaf to control wrap-up), maintain a stock Z/28 ride height, and 200lb spring rate.

What do you guys think? Is 200lb too much for street (and a couple trips a year to the drags)? And how exactly should I make the bottom leaf (to control the wheelhop)?

OH, one more thing. What size (length) U-bolt should I use with 3 leaf springs? I also need to know the diameter of the 'U'.
Thanks!
Matt

All the U-bolts I've seen are the same size. If they are to long, you just cut the excess off, after the nuts are on.

If you like I can send you the dimensions of the Hotchkis rears I have.

Search for messages here by chicane67, he designed his own rear springs that are working really well and are similar to Guldstrand leaf's. He is using a rate over 300 lbs, which is REALLY stiff! But he says it's fine.
Hotchkis are around 160-170 lbs according to my measurements. A 200 lb spring is probably OK.
Betts is a well known company and delivers to many many truck repair shops down here.
You have Renton Coil Spring Co there too!

David-
I searched for Chicane's springs and I didn't find too much. What was his leaf arrangement?

I'm still playing with the spring rate. I gone from 125, to 140, then 150, and now I think I'm back at 125. Gee whiz. I want really good weight transfer on acceleration, but I don't want it to handle like a pig. I also have 380# front coils. What do you think?

I called Renton Spring, but unfortunately they don't make leaf springs, just coil. Bummer.

And yes, I'll be at the Super Chev at SIR (can't get used to Pacific Raceway). I will also be going to the Monroe swapmeet that's coming up soon. Hey, if you want, just drop by, I'll give you directions.

I got my springs today! They look well made, and they got the leafs to be exactly the way I wanted them to be (longer bottom leaf). I will be installing them shortly, so I'll let you know how the ride height is. The spring rate is around 160 lbs.
