On early Chevrolet™ and GMC™ trucks with 4-piece hoods, one question often is raised: How to securely hold the hood open? There is nothing more aggravating (and possibly dangerous) than to have the hood slip off the cowl and come slamming down.
The other solution is to open the hood completely and rest it on the hood panel on the other side. This can scratch the hood panels, and does not allow both sides of the hood to be opened at the same time.
The best solution is to prop the hood open. From all indications, the hood prop shown in this document may have been a factory item, but in many cases these have been lost over the years.
When the hood is opened, the prop mounted on the core (radiator) support rod is pivoted up, and the hood latch rod is placed in the notch at the end of the prop.

When lowering the hood, the hood prop is pivoted in. The tab welded on the arm will rest against the cowl to hold it in place when not in use.

NOTE: In some applications, items mounted high on the firewall may not allow the hood prop to rest against the firewall when pivoted to the storage position.
The hood prop is mounted on the core support rod, and is held from moving front-to-rear by a jam nut in the opening formed at the end of the hood prop arm. To install the hood prop (see pdf file - the installation drawing goes along with these instructions ):
NOTE: Before removing the core support rod, record the amount of threads exposed beyond the outer (engine side) nut. This will provide a starting point for adjusting the hood during assembly.
For installing drawing and the Parts and Assembly Drawings, download Randy's pdf file. The images and layout are excellent.
