Resto manual

So lets put it this way. You have several holes in the rocker panel or floor pan you're looking at. With some time you can identify what goes into such and such hole. You can also get the pat number, if there is one, for the part. So to that extent it may be useful.

I beleive there are some differences between '67, '68 and '69.
The emergency brake cable may have been run a little different. The fuel line route seems similar but the attachement locations seem slightly different.

For $35 it might be worth having. Close to 500 pages.

The 69 engine equipment assembly book probably is not. Most of those drawings are same as you see in other factory literature. Its just over 70 pages
