Technical 55 Chev convertible

I'm trying to find a picture of the frame dimensions for a 55 Chev convertible. Only one I can find online is too hard to read.

 

This help any? Frames are the same dimensionally, only the added mounts and x member for convertibles

 

Scott, my '55 HT is on the lift. Not a 'vert, but I'm happy to measure if that can help.

 

Thank you!

 

Thanks. I'll let you know. I'm actually working on a 56 Olds convertible. I don't have a convertible frame, but it has an X member that appears to be the same as the Chevy X member. I see I can buy the X member as an aftermarket. Just trying to get an idea if the X members are the same so I could splice one into my hardtop frame. I know the Olds already has an X member, but I've been told the convertible X member is a much heavier gauge steel.

 

The old Tru-Way frame dimension book shows a few differences between the convertible and regular frame, but be cautious as some of those measurements are taken from different points.

 

For bonus points, here’s your front end alignment specs. Lol

 

does the book have the Olds frame? that's the $64 question

 

Guess I did my speed reading and overlooked that. Sorry.

 

looks like the Chevy X is a few inches short for an Olds

 

That's what I'm thinking too. I'd love to physically lay eyes on a convertible frame to see just how much heavier gauge it is. Is it in the actual X member or just the steel plate under the center of the X. I know that plate is at least 1/2"-5/8". I may be able to get away with just boxing things.

 

I think I have posted these pics for you before. I no longer have the ch***is so can't measure the thickness for you sorry.

 

I had a 56 98 coupe as well and from memory the whole Starfire X member was thicker. I would guess twice as thick as the coupe X member.

 

Thanks again. I still can't find a ch***is so I'm going to have to improvise. When I saw they made an X member for the Chevy convertible I was hopeful, but it's not looking like it will work. Perseverance. I will fully box and gusset the heck out of the hardtop frame. Might be stronger than the original frame by the time I'm done.

Would you happen to have a diagram for a 53 Olds convertible? I found one of those but not sure how close they are.

 

I will look when I get to the shop this morning. I do remember that the earliest Tru-Way book I have covers the 46-53 models, and then starting in 54, the books only covered one year. So, the early book may be limited in what particular models it covers. I will post a pic if one is in there.

 

There’s no mention of a convertible on these drawings

 

Thank you. That looks close enough that it might work.

 

You’re very welcome. Good luck with your project.

 

Scroll down to 61/97 They give feame thickness and other info there.
