Question about availability of parts for a 69 Dodge Coronet/RT Convertibles
 

Been looking around for a 68-69 Convertible. Been mainly looking at the Plymouth's but have run across a couple 69 Dodge's.....one being a Coronet. Like the way the R/T's look better though (grill, trim, etc...) anyway was wondering if the R/T grill's and trim pieces are available at the reproduction part's supplier's (year One, Classic Industries, etc...) so if I did decide to buy a Coronet what all would need to be changed to make it look like a R/T? Would any interior changes be needed? Thanks
