Heres a photo which aint the best,
I want to say they are 6inch? unless anyone know i guess ill have to remove.

Welcome to the forum
5 to 5.5" , the only factory 6" was the RS 4 spokes on mk2

Thank you, next Question is with 205/60/13 will they fit on factory gaurds?

Many factors to consider, they should be ok on 5.5" but the road feel will suffer slightly due to the side wall flex, this is worse on 5" rims . Check the inside rim to sit leg gap as that's where things start to rub first, the outside should be fine and might need a little arch rolling to reduce scraping.
My MK2 used to run 7" with 205x60 and it scraped everywhere even after rolling and lightly flaring the arch. A lot of us here with 13s use 185x60/65 tyres whether the rims are 5" or 7" wide .

Thank you my friend

they handle far better on these proper peiod tyres compared to modern tyre carcasses, yes tarmac racing cars did fit 205/60R13 tyres but they were very modified to try to keep the foot print on the road. all sorts of things that make for not a very nice road car,

fitting these proper tyres is to improve the handling.
 
If it is just for a concourse car then an ny old tyre will do.
