I have HD on my 84 & 85SD and like them. My other vehicles are a 00 Diesel Ram and 78 Datsun Z. I prefer stiffer suspensions & find the SD ride very comfortable.

I have a set of good front comforts that I removed from the 84 if anyone has a need. The rears were shot & I replaced all 4. Professor Google looked up the part number for the existing fronts once I had the part in-hand.
