1968 Plymouth Barracuda Fastback (old school build with a new school feel)

I like that you are sticking with 15" rims .

To me big modern wheels on a muscle car is like a halter top and short shorts on a 60 year old woman .... just looks out of place .
Yes I went with 15” rims on my ‘69 and they do look right, only thing is 15” tire selection is getting scarce. Only a few choices besides besides BFGs, especially if you want blackwalls - unless you’re ok with buying Chinese. Next time I’ll go for 16”
