If I can't get the plastic retainers to hold it properly I'm going to switch to nuts and bolts.
I'm hoping to re-install my dash today. I removed it about 2 weeks ago to install a painless wiring harness.
I'm also installing a new heater box, heater hoses, new heater valve, tuffy glovebox, defrost ducts, and some auto meter gauges that I bought back in 2016.
