Reverse are lil wider for fitment.but they should fit. On my 73Monte for my "Rollers" i have Reverse 14x7 on Fronts & Standard 14x7 on rear. Special events, Family outings, Cruises, etc i run coker 520ww/13x7 D's Safety wise the DOT standards i think recommend no less than 15" for vehicles in size such as ours. But as for safety concerns its reallly not much difference to have 14s vs. 13"
I know 13s are "traditional". 79 LinCons have huge fender wells so depends on your taste in looks. Majority run 13" to keep it traditional while others prefer to run bigger bcuz they might not like seeing the extra space between fender & wheel. Ive 79 Marks on 15", 14" &13".
