Good luck. Chev's of the 40s has them. As far as any other repop grill pieces for the 52 they are slim pickens. I went my own route and did a custom grill using draw pull handles and painting the grill pieces. Mine were pretty bad off. Good luck.
ouch,went to the dentist yesterday and teeth still hurt - oh ya, were you going to post a pic of what you have or are you looking for some? if looking for some try a Wanted ad here.
