Value of 67 Camaro kph speedo?

[PeteLeathersac]

Speedos here in Canada didn't change to KPH 'till the mid 70's so our musclecar era factory stuff the same as USA.
The conversion decals were later too also largely aftermarket, it was a foolish time w/ stickers on everyone's speedo heads although exciting seeing the new speed limit signs w/ Maximum 100 on them!
Not specifically '67 Camaro but I've seen a few 60's GM used 200 Kph heads in recent years around $300 also more when genuine Nos so would $500 be a fair offer?
Also, are Kph faces only available repop to convert the head then swap drive gear to suit?
