Hi,
I was at the bone yard the other day and found some sr5s with good gauge clusters,tach, oil, temp, from what I understand you can just swap these with your non-sr5 to get a working tach and other guages I think they were 4cyl trucks but I could be wrong. They aren't much use to me but if people want them I can grab them. I found them selling for $100+ on ebay,if any body wants them or knows that they do or don't work please let me know.
