 My front forks (1994 XLH Std) were in need of rebuilding. So I purchased all the wearable parts and disassembled both front forks. I replaced all these parts and put new fluid in the forks - I used a no-name ATF for the fork oil, it being about 5-10wt oil.
-At the same time, I replaced my stock fork springs with the Progressive 11-1527 springs. This spring kit is designated for rubbermount models, but the spring specs match for 91-later models as well. But the spacer needed to be shortened.

-(I have not actually measured any of the other kits, but if they\\
-include the same spring with simply different length spacers, you\\
-could buy any of these kits that were offered for a good price &\\
-then make your own spacer for your own forks. A possibility?)\\
-==========================================================\\
 Some notes from my install - I have learned much from the XLForum - The following tips were especially helpful:
-) Loosen (not remove) the Damper Bolts while the forks are still on the bike & under spring tension

-) Align the fork cap on the slider tube (no springs installed) and mark the exact point (on both the cap and the slider) where the threads begin to engage - This tip was extremely helpful in getting the cap back on while compressing the spring

 The stock springs stuck out of the extended fork slider by 1-3/8"\\
 The 1527 kit spacer stuck out of the extended fork slider by 1-1/4"\\

-The spacer included with the springs was 3.00" long x 1.054" in dia (ID .813").
+The damper bolts in the rebuild kit I bought (Bikers Choice Fork Seal Kit) had heads that were too long to clear the axle opening in the right leg - When fully inserted, the bolt head stuck out into the axle cavity. The existing bolt heads were .509" in dia & .237" thick - the new ones were .518" in dia & .312" thick. When I tried a new one in the left leg, it fit OK. But I opted to use both the old bolts (thoroughly cleaned) with the new copper washers.

 Someone had put silicone up into the damper bolt holes (presumably to stop a leak) - what a mess. It took me an hour of scraping with a flat-blade screwdriver to clean that stuff out of the bolt hole and the surrounding area. The new copper washers crushed & sealed the bolt holes just as they should.
