Replace starter cables

Hello together, with my oldie (Jaguar) it turned out that the cable from the LiMa to the starter is already quite age-weak (runs directly next to the engine), i.e. the external insulation is quite stiff and crumbling, there are already two cracks in it. The problem is: the cable is no longer available to buy. Now my thought was that one could simply take electric cable as a meter-ware and attach ring cable shoes to both ends to connect it in the car. guess I, cable is not the same cable, so what do I have to pay attention to? As far as electrical equipment is concerned, I am rather unnecessary, I only know that the starter has 1.8Kw according to the spare parts catalog and the LiMa probably 120A, can be derived from this somewhat regarding the quality of the cable? Greetings Olli
