67-72 Radiator supports (n00b alert)

[ugotd8]

Hi guys, I'm a little confused. I just bought my first truck, a '72 (http://67-72chevytrucks.com/vboard/s...d.php?t=206571) and I'm starting the resto-rod conversion. I've collected a '68 hood and two '67 fenders. I have to rip off the old front clip this week, since the motor needs a timing chain. I've done some research here and read that I will need to change my radiator support as well. One thing though, this truck I have has the turn signals attached to the radiator support where they would seem to be on a 67-68. I thought the turn signals were supposed to be in the front bumper and expected a jerrry-rig, but the turn signal housings are mounted in stock holes and there is even a molded opening for the wiring plug. I know this truck has a 69-72 hood and a 71-72 outer grille shell, although the outer grille shell is riveted everywhere (did Chevy do that?). So, I have some questions:

1. How can I tell 67-68 and 69-72 radiator supports apart?

2. I am commited to going to the 67-68 front sheetmetal, do I absolutely have to change the radiator support?

3. Can I use my inner fender wells on the 67-68 fenders?

4. How can I tell 67-68 fenders apart from 69-72 fenders off the truck?

Thanks in advance.

well i can answer 2 of ur questions the fender wells are interchangable through 67-72, and the way you tell the diff between 67-68 from 69-72 fenders is that 67-68 did not have side markers on the front of the fender unlike 69-72 where all of them came with side markers. Now as far as the rad support is concerned i believe it has to do the way it is angle'd im prob wrong but since the 67-68 hood is sloped, it will not match up to the 69-72 rad support cause they have a more Blunt nose to them. so you will need to change ur rad support or u can do some hectic modding lol anybody correct me if i am wrong...

Only 67 fenders did not have side markers, in 68 they did but have the same shape as the 67's. The front of the 69-72 fenders have a recess cut in the front leading edge of them so the grilles will fit over the fenders. Core supports are different as well. Check to see if the core support you have has a splash pan bolted to the bottom of the core support. That would indicate that it is a 67-68.

67 - 68 had the turn signals mounted in the center section of the grill of the grill. I have a 69 and the turn signals are mounted to the rad support. One real easy way to tell what year your support is from. 69 -72 had headlight brackets spot welded to the support to extend to the lights forward to match up with grill.
