Inner wings so need to be modified, 1/2" lip removed. I used a cut off wheel in my $13.95 Harbor Freight Angle Grinder. Fixed that issue in about 10 minutes per side. Change to a grinder wheel and made flush, painted and no issue.
Now converting to front tilting bonnet as I did with Bugsy my '68 is more challenging as lots of parts and pieces need to be closely aligned. You can make the front hinge set yourself. Takes about $40-50 of misc parts, drill press, angle grinder, flat files, some 1/4" aluminum stock onr as I did several thinner pieces sandwiched and JB Welded together.
Oil cooler will need to be relocated if you have one. I can send pics on how I did with mine. Wiring a simple trailer harness as a Quick disconnect.
Rear Bonnet seal, McGregor's in Canada. Supports back of bonnet if front hinged
It helps to have a straight, properly curved bonnet rather than the pool table straight bonnet I purchased. They are actually arched to match the cowl. That has been the biggest fitment issue I'm still working through, that and my repair work on bottom rear of bonnet I need to redo properly.
