I think the "issue" with regard to springs that fit Triumphs is that 
Triumph used an ID that is somewhat unique.

If you "convert" to a stock diameter spring (like 2.5"), then changing 
springs is a piece of cake (and almost cheap). 2.5" is good because a lot 
of coil-over threaded bodies are 2.5". Please note that I'm not suggesting 
that you convert to coil overs, although I'm sure there are those on the 
list that have. But changing the spring perches to 2.5" ID springs really 
changes what options you have for spring rates.
