Hey I know this aint about suspension, but I and others had problems with finding front end (lift kits, control arms, etc) aftermarket parts for the 99-00 2500 non-HD 4x4 models, do you know what years or other models have interchangeable parts or what companies make parts for these models? Or how I can find info on that?

my 05 Tahoe has 84,000 miles on it and I'm getting ready to replace the plugs, I got the iridium AC Delco but for the wires I'm going to use MSD 8.5 mm, or would it be better to stick with the AC Delco wires?

Boat tech here YES to the dielectric grease. Better long term connections and easier service later. 👍
