I have , obviously , done the hoop method as above ..but another way I have done it is to use the front tube as the pivot ,
sleeving another piece of tube over it and welding it to a short piece of 20mm or 25mm box that welds the bonnet end to a 5mm plate bolted through the front ..it is attached with a domehead bolt just under the indicator position generally ..
you will need to trim some of the front valance away to get clearance on the front chassis rails ... it becomes obvious when you try to open it !!
The Formosa is a similar system , but the deep rounded front valance and hugging arches makes them a bit more complicated ..
