the car might have had a light knock in the past. if thats the case it will be relatively easy to bend the slam pannel holding the catch into place. its not like you have to bend it a long way. you wil prob be able to do it with a mates help. failing that just take out the latch and re - drill the holes in a lower location.
job done!!

Cheers for the replies :Thumbs-up 100% sure its not the bumper as i have had three different bumpers on and the bonnet never needed to be moved its allways been spot on also 100% sure its not been crunched at some point I was just wondering if anyone had found this before on a aftermarket bonnet and how they fixed the problem or if there was a difference in years to how the bonnet sits one thing i did notice the car the bonnet was coming off was missing its middle support bracket for the latch im guessing this must be how the catch is moved low enough to fit it seems a bit naff to me if thats what you have to do to get it to sit right

Could be a few things,

Ask the previous owner if it fitted his car ?

First thing I would do is unbolt the bonnet catch on the body completly then see if the bonnet shuts with no catch as this will show if this bonnet is ever going to fit.

If it does fit then you have two choices, either remove the catch on the bonnet if its not bonded in and have it cut and welded or cut slots in the catch on the body to drop it then use washers to clamp it back on.

Lastly if you have a standard front you should be able to stand at the front of the car and pull up the edge a bit as this is something I have done on both RX-7\'s and RX8s to line up the front panel to the bonnet line

You should ALWAYS use bonnets pins on GRP/CF bonnets (back up to the main catch or not).. Have been a few nasty accidents due to the GRP/CF catch not being able to withstand an unfortunate crosswind!
Besides.. they look cool :D
