1993 SunSport Gauges

[TetherEd]

I have a 1993 Sunsport that has some issue with cracked gagues for the oil pressure and temp. I would like to replace all of the smaller ones. While they are teleflex gauges, they don't seem to be standard ones as found on many other models. They mount behind the dash and are basically flush. Do you know if I can still get these?

One other issue. At high RPM's, the oil pressure jumps from normal to 0 back and forth. Does this seem like an engine issue or could be be a sender problem?

Thanks!
