I actually bought the post car because it was about $50 cheaper than ht and used that to buy the AM radio. I was going as cheap as possible but getting the most bang for the buck. Had no clue how unique it would be. Thrashed it, sold it then had opportunity about 10 yrs later bo buy back. I put the story here if you want to go read it.

If you do any searches there on the PY forum in the 70-72 GTO/Tempest/LeMans area there is plenty of good information there.
