Have any buddies that work at autobody shops? I'm sure they'll have a compairable year truck in for repairs to the front end sooner or later... if you could spend an hour or two with a tape measure and note pad, you'd be set, even 20 to 30 minutes would give ya somthing to go on... all you'd need is some quality time with someone else's truck with it's bumper down, er, off... be careful, some one might get jelous...
I may go this route myself... I've done alot of electrical work in the local shop, I know they'd let me check out a truck in for repairs when they had one...
That's really cool that you'd share what you come up with for your truck, it's the best way to come up with great ideas, copy the best parts of other's great ideas! Thanks!
