First of all, this seems to be a great informational site with great members. Keep up the good work! I just picked up an almost mint 1977 GMC Suburban K25 a couple of weeks ago in an auction for the mere price of $625. It runs perfectly; has a 305 V8 (didn't think Burbans were available with a 305) and a 3spd manual (although not sure on that, goes from L-1-2-3, technically a 4spd?). Exterior is in great condition, newer paint, custom full-length roofrack and unique custom rear bumper. Interior is in good condition also, a few cracks in the front vinyl bench and a missing window handle. It runs on a set of Wildcat EXT mud terrains which roughly size out to 32" tall, 9.5" wide (245/85R16). It's unknown whether it has 180k or 80k (280k for that matter), but it drives like new. Steering is still pretty tight and it was very quiet when I first bought it (after inspection, pipe came disconnected during a wheeling adventure and now sounds much meaner). The truck is awesome, and this is coming from a Ford addict. /forums/images/graemlins/peace.gif It does have some quirks, one of which has gotten me pulled over three times in the past week. When using my right turn signal, my right reverse light blinks instead of my taillight. What is causing this? My left blinker works just fine. My speedometer stopped working a couple of days ago. All of the other gauges work fine. Wasn't doing anything too rough between the time it did work and the time I noticed it not working. I did tackle and park on a rutted soft dirt hill, but I wasn't going fast enough to knock anything out of place. Any suggestions on what to look for as far as the cause?
