65 chevelle wheels

[USAZR1]

is his car stock hight? i was going to lower mine 2-3 do u think it will still work? or will i prolly need a smaller sidewall hight? also it will be a 17-8 not 9.5 and the rims have 4-1/2 back spacing

Dave's Elky is lowered probably 2". You should be fine but 5" backspace would be a little better choice on those 8" rear wheels. 64-65's like a little more BS than the later cars.
