I did my 68 front about a week ago. Yeah kinda a pain - I couldn't get my fender upper front triangle parts off (the parts of fender that mount to bumper support). Those crazy large phillips screws would not come out and I didnt feel like cutting them off ect.
They certainly look like phillips screws but they are actually number 4 Pozidrive screws and take a special Pozidrive driver for the best chance of removing them.
