For those who are not aware of the site gmpartswiki.com, that site has a pretty large selection of GM parts and illustrations books available on line for free. Most are Chevy books, but of interest to this group is the April 1962 update to the Oldsmobile parts and accessories catalog. The cover page says Dec 1961, but it actually is the April 62 update, so it does have the 62 Jetfire info. I’ve attached a few illustrations of interest. Enjoy.
Unfortunately the site isn’t that user friendly, so you do have to go page-by-page. You can also jump to the next section using the hyperlinks in the upper RH and LH corners of the page. Also, there is a search function that lets you search terms or group numbers.
Also,there is a table of contents at the beginning and you can guess what page you want and go back and forth a little to dial it in by changing the page number up in the browser. Still tedious but a lot quicker than page by page.
Unfortunately, the page numbers in the browser URL aren’t sequential and don’t correspond to anything. I have no idea why they did this, but it is just stupid. The Search function is the easiest way to navigate.
