Dolphin gauges are fine for the cost an look good.Its just what you want to pay.I bruoght reconditioned gauges for my 51 for 500.To tell ya the truth they aren't worth a darn..they look good just setting there in the dash.But under the dash are a set of Walmart gauges for 10 bucks.an they work fine for the time.The guy I brought the reconditioned ones from said just return them for a replacement.I can't stand on my head anymore.the gauges are a [censored] to remove unless you eyes are in good shape.Also the warrenty,I brought them 3years before I installed them.So don't buy things ahead of time.you only screw yourself down the road on the warrenty
