Trying to get new fenders to fit

[badherb]

Purchased left and right fender for my 60 SWB tri plus automotive from LMC truck fenders. They fit like crap. Gap at door is wrong out like a quarter of an inch. Can’t seem to get the front inner grill support to bolt up. one side fits better than the other but they still both suck anybody else have this experience? Can you point me to a post for a how to fix these pos. More interested in a fix but just feel like these must not fit well on anyone’s truck. Yer experience will make me feel like I didn’t get ripped off. OG fenders fit great just too rotted out. Would have spent weeks getting them better. Just didn’t want to spend all my time on a skill I’m not great at and here I am doing something I’m not good at. I’ll post pics when I’m sober and starting my day rather than looking at a pile of work I’m not sure how to fix. Any help is appreciated.
