The straps I got from
www.fibre-lyte.co.uk. , yeah you are correct I had to put some longer screws for the rear , I also had to put a small spacer where the old nut went . As for the front I think I used some post from a tamiya f1, I just had them lying around . I know some one who also had these who used b44 posts and thumb screws. Hope this helps , let me know if you want any more info .
