Your original trim rings should be able to be re-chromed as long as the rust is only surface. Will have to check the ones I have as I seem to recall them being stainless steel like the HG GTS hubcaps..... :confused:
the rims are not the same from hq thru to hz....hq up to end of 73 was a canadian manufactured rim specifically taken from pontiacs...the centre star piece is more defined on its edges and you have stamping next to the valves on the outer edge...
74 on they are made by roh in australia and the stampings and date codes are under the tyre..the star section is less defined on its edges...
trim rings for hq are square edged...none are rounded edges...trim rings were also an accessory and not factory fitted equipment..
