doors

hey everybody i am new to this website. any way. i have a 1976 cj-7 F-glass hardtop on my 90 jeep YJ i do not have doors though. i was wondering if i should purchase either YJ doors or CJ doors. i've been told it doesnt really matter because the overall construction of both jeeps were the same. any help would be appreciated.
Thanks~kyle

it dont matter just get CJ7 or YJ doors which ever ones u can find for cheaper
