if layed my eyes on thes rims :

i did some reseach and i think i can make them fit , however i'm not sure

these wheeels are 15" bolt pattern 4 x 100 but i think that can be solved with "springnuts" (free translation)
springnuts:

the centerholes of thes rims are 73 mm fiat 124 has 58,5 mm. but this can besolved with a centerring :
centerring :

these are 15" 7j 25 mm offset :

and the lenso s are 15" 7j 25 mm offset , if combined with a 195/50/15 tyre , then they have a perpendicular of 1760 mm

the tyres i have now are 175/70/13 so that would make a difference of 50 mm
