We've got an SPF here in our paint shop now. It is being RErepaired properly this time after suffering very similar damage. The first guy glued the parts together and they were covered with stress cracks. The lower centre section is still weeping
oil and coolant out of the glass from where the cooler and radiator ruptured. It had to be completely remade from a pull off the shape. Yours may be easier to put a front clip on if they are available. Have a good fibreglass guy look it over real closely. Maybe a Vette shop or a boat/jet ski place. Good luck with it and keep us posted.
