Thanks for your input. How long have these units been in your vehicle?I was looking for replacements for my 86 and went with Nu-Relics. I live in NC and its a NC company. I emailed them and asked about coming by. They had the regulators ready for me when I arrived. I can’t express how nice these people are! The owner greeted me, introduced me to office staff and gave me a tour of the shop. Gave me a couple of extra wire connections just in case and spoke about grease to use, etc. Anyway, they went in without issue and work well so far.
