I would not recommend them unless the new pressure sensors are more reliable than the old ones which I have/had in my truck:
"Autometer mechanical boost and SPA dual gauges (boost, trans temp & fuel pressure, intercooler temp). Also, gauge power switches (to reset max stored values in SPA's) and TCC lock up switch."
I removed both of them from my truck several years ago. That was $600 plus down the crapper. If I feel froggy someday, I *might* shell out the $200 plus they want for two new pressure senders and have another go at it...
