Well, I rang Chic Doig, really helpful bloke, gave me a few pointers and said start with the door and build the sills etc to match up the panel gaps, makes sense, ordered the lot from him, outer heritage sills 83ish plus vat but he's giving discount etc on the stuff he can do like door bottom repair and extended at the front up to the hingeπ
Re heritage stuff yes I've had some varying fits on minis and midget panels, all adjustable etc, but the good thing with them is the steel grade is better, the worst I've had were a mini MK2 done just before the GT6, the inner A panel hinge parts didn't line up with the outer ones and had to cut them out and move about 40mm, you get to know which panels fit best once you've done a few etc, if I had to do that MK2 again I'd use pattern inners and heritage outers, but at least we can still get panels so happy days.
Only thing I didn't buy was a floor section, I'd rather fabricate the 60mm wide section than change the whole panel as the rest is good. Pity you can't get that as a section.
Once again thanks for all input very appreciated π
