possible front caliper substitute for 1980 se U.S custom?

[walleye]

I've now almost got my xs400 street tracker sorted but have a problem with my front caliper.
I have the big caliper thats on the xs400 se us custom and the bolt has seized that the caliper pivots on. I am currently trying to free it up by intermittently spraying and letting it soak with fine oil.
In the mean time does anyone know if the other xs model front brake calipers will fit the mounting on the se forks?

Go to www.cyclepartsnation.com and find your part, copy and paste the number in a part number search and it will show all the other bikes that use the same part.
