OK here's a couple of questions that I don't really hear much talk about: - I have a set of 3:42's going into my truck. My speedo is going to be off now on the high side. Is there a specific cable that the trucks with this ratio had? Mine is a 4:10 now. I'd like it to read correctly, or at least in the ballpark. - I was planning on using the 20R distributor on my new 22R I'm slapping in since it's a direct drop in and no mods needed. Is there any advantage to going to the 22R distributor and swapping out the ignitor / coil? I'm figuring probably about the same either way. Just wondering. I know in the old days you'd just take it to a place that does speedos, but do they even do that now in the days of VSS? I'm not planning on changing from the 3:42's ever so I'd like to make this permament. I found this article, but do they sell the gears still thru the dealer?
