Hey chong, well to my best translation it will fit all 52mm defi's so it should fit, i will get one in and if it fits great and if not then i will just cop it!

With the radiator and alternator covers i got the same sort of answer, they think the alternator cover will fit but have never tried nor can they try as they don't have many gc8's so i will get an extra one in and hopefully one of you can be the tester with a discount
