ManicMechanic Posted January 18, 2019 Report Posted January 18, 2019 Gentleman named Paul bought a bunch of Oldsmobile drafting papers and these were among them. jiggity76, oldmangrimes, rich_e777 and 3 others 5 1 Quote
jiggity76 Posted January 18, 2019 Report Posted January 18, 2019 So are these developmental drawings for engineering purposes? Pretty neat! Quote
K&R Posted January 19, 2019 Report Posted January 19, 2019 The “roll bar” is a unique design on these. Was it originally designed for a roll over crash or extra body support since some ‘88s didn’t have the bar. Quote
ManicMechanic Posted January 19, 2019 Author Report Posted January 19, 2019 The '88s that did not get it were true roadsters, no top at all. The "basket handle" offers zero protection in the event of a rollover. Quote

The b-pillar was reinforced but between the pillars was just the same metal that was there when it began life as a coupe. jiggity76 1 Quote
Imp558 Posted January 19, 2019 Report Posted January 19, 2019 Someone was talking a while ago about the notches cut on either side of the engine bay on a 'vert. I assume those were to provide more crumple in a front end collision. Makes me wonder what other little things like that are in place that haven't been noticed. Quote
K&R Posted January 19, 2019 Report Posted January 19, 2019 Wow!! So 1990 is the first full production year for the convertible. So the weak structure caught GM off guard and that’s why their aren’t any 1989 convertibles so they had to push it back to 1990? Quote

K&R Posted January 19, 2019 Report Posted January 19, 2019 Oh wow. The handle was just a quick fix then through the whole production! So I noticed the Chrysler PT Cuiser has the handle as well. Do you know if they did the same thing or is there extra support underneath? Quote
MemphisMan Posted January 19, 2019 Report Posted January 19, 2019 These are great illustrations Manic. Thanks for posting them. Looks like they assigned individuals by name to fabricate different support pieces.In the back of the 1991 CS Service Manual Vol 2, there is a section which shows all of the reinforcements added to the coupes to make them convertibles. I counted 30 diagrams and each diagram appears to show a different support brace and it’s location on the car. I’d post all of them in a separate link, but my manual looks like termites got in it and the entire section of the manual is damaged. If someone could post up the diagrams in the Vert section that would be great. Here are just some of the diagrams.Sent from my iPhone using Tapatalk K&R and jiggity76 2 Quote

Any ideas? Quote
MemphisMan Posted January 20, 2019 Report Posted January 20, 2019 Hmmm, if you have MS Office, you can rotate them in picture viewer then upload them. If not, PM them to me and I can rotate them?Sent from my iPhone using Tapatalk Quote
jiggity76 Posted January 20, 2019 Report Posted January 20, 2019 Ok, thank you. I have to do some errands this morning so it will be later this afternoon. I'll let you know when I send them to you. Quote
Imp558 Posted January 20, 2019 Report Posted January 20, 2019 GIMP is a free download and one of it's many options is image orientation. Quote
sean1991olds Posted February 14, 2019 Report Posted February 14, 2019 Really cool pics of those drafts!! Amazing what drawing skills people have.. Also cool to see where the reinforcements are exactly, I do have that Vol.2 - never knew it contained those vert reinforcement locations. I was recently watching an old GM video and I remember them talking about another model that also skipped a year to sort out the convertible reinforcement stuff. I was just interested to hear that it wasn't strictly an Olds problem heh. Quote
