How do I reach out to hd-dude and prodrag1320 to get their insight?
Since hd-dude, prodrag1320, and HD Street Performance have posted in this thread, you can go to their post and use #2 below. For bvhog, use #1 below. You can look up any member by their screen name using #1:
1. Use the "search" box at the top of each page, then click on the title of any of the results; or
2. On the left-hand side of each post, below the name, status, avatar, etc., there are some icons. Click on the envelope-shape to get their email, or the conversation-bubble to send a PM (private msg) through the forum, or the person-shape to go to their profile, which will have those plus more.
