Changing front clip on my 73 scamp, need info...

one thing you may need to watch out for is in 69 they didnt have side marker lights. they are only reflectors, if you need to pass inspection for the 73 model year you will fail(if the inspection mechanic is competent). 67 or 68 one had none and and the other had little round lights(I dont remember which is which though). 70 and 71 have side markers that are diffrent than your 73.
As you stated you will need the entire clip not just the grill.
