The rotor bolts are not standard bolts at all, so you will not likely find replacements easily. They are special "Shoulder Bolts". I don't know about the '02 and later LTs, but the bolts for the calipers on the earlier ones could possibly be replaced with somewhat standard hardware.
If you must, you can just get another set and have them chromed. Be VERY aware though that if the plating shop is not a VERY GOOD one, with the proper process controls, that chrome plating improperly done can cause
"Hydrogen Emvrittlement". That is a nasty little thing that can cause the parts to crack later. For that reason, I myself would NEVER put chrome plated bolts in any critical area.
Avoid Stainless Steel also, as it is much weaker than the standard bolts used for the calipers. I think I remember that the caliper bolts were grade 10.9. Should be stamped on the head. If they are grade 8.8, then a good stainless bolt will be about the same strength, only slightly weaker. However, the caliper bolts are threaded into aluminum, and stainless in aluminum can cause severe galling of the threads.
