Well I contacted diawa yesterday asking if the did a trolley/wheel kit and this Is what they said
Good afternoon,
We do not do a wheel kit specific to the D75SB. I can confirm that the closest item we do is the TDTT1. This is NOT specifically for this box but it does fit onto it, even if it is not a perfect fit.
Best regards,
Garry Reynolds
Wow what a lot of help that was....why sell a box with out a suitable trolley or wheel kit....I for one is never buying another diawa product.....anyone want to but some diawa tackle :-(
