85-92 Lowering spring length?

[Streetfighterkz]

So I bought the Progressive lowering spring kit (10-1556) for my '89. I also watched Sean's video about fork reassembly where he noted the Progressive springs were 1/4" taller. I measured mine and they were 5/8"-3/4" shorter than the stock springs. I realize Sean was working on the later 43mm forks rather than the earlier 40mm units, but something seems off to me.

Any suggestions?

Just as an FYI, I put everything together using the stock spacer length and a 1" lowering spring. This gave me an extra 1/4-3/8" of preload I suppose. The bike handles better but I think the preload is a bit much even with me being 220+ suited up. It is liveable but I'll probably cut the spacers down some at a layer point as riding season is in full swing now.
