mondial wheel specs

Hi all, I am in the process of looking at replacing the stock wheels on my 85 Mondial QV as the price of tyres in the 390 rim size scares me, my question is I have been looking for the stud pattern and offset size and have found this to be, 5x108 and a +55 offset, can anyone confirm this or am I way off track, its a bit hard to exactly get the rims I want without knowing this info for sure, thanks in advance for any help given

thanks for that, I am leaning towards these wheels, I have done a quick photo shop and think it looks hot
