aftermarket panel fit problems

[evilzee28]

The front of my '69 Camaro has original GM front fenders with after market inner fenders & an after market radiator support panel. I first fixed the fenders to the rad support & bolted up all of the rest of the sheet metalwork, but didn't fit the inner fenders at this point. Everything appeared to line up pretty much ok. On disassembling the front body panels & fitting the inner fenders to the fenders, I found that the inner fenders didn't fit too well at all, but manged to get them looking ok after a bit of work.
On fitting the assembled front fenders/inner fenders to the rad support I find now that there's a big gap at the bottom of the fender next to the door bottom, it's as if the front end needs to drop to fit properly & to close up the gap at the rear of the fender.
I'm sure someone had problems with an after market rad support, ( I think it might have been Scott?) was it found to be too tall? What should the distance be between the point where the fender bolts to the rad support & the top of the front clip/chassis?? Thanks guys

ps it's got aluminum bushes on the rad support.
