The width of the spring leaves is not critical as long as they fit your application otherwise (length & center pin location). If you are putting these in the stock 1927 Chevy location and the original springs were wider, you will need to put shims (washers) on the sides to make up the difference in width. You may find that the 1,000 pound weight rating is too stiff for the vehicle, especially if you are using two springs in parallel like the stock Chevy. No problem, though; once you determine what the ride is like you can delete leaves to soften the ride or add leave to stiffen it.

I am using boat trailer springs in the back of my roadster. I bought them at the local ACE Hardware and cut one end off to make quarter-elliptic springs. If they are too stiff I can remove a leaf or two. Also, by using shackles that have multiple holes, I can change ride height.

One last thing, the ride characteristics of a leaf spring can be improved by disassembling the spring and rounding off the ends of the leaves slightly. When you put the spring back together, put Teflon strips between the leaves (available from Speedway, Posies, etc.) or, at very least, lubricate the leaves where they touch with heavy grease.
