71 Duster Dash Pads

I’m still searching a decent price on a Dash Pad. Just Dashes told me $1000 plus. Classic Ind, PG n Year 1 plus others have them under $400. Most say it has a steel core n requires a core charge or ship your old core back which I hate to do because of the UPS oversize shipping cost.
Seems like a lot of companies just Drop Ship from the manufacture. I’d rather go the the source. Does anyone know who the best manufacture are? I also read on Abodies to stay away from the plastic core n that some Dash Pads don’t have the corner attaching studs. Anyone know or have had experience so I don’t screw up?
Thanks
