I would suggest rack and pinion steering,

How are you going to brace the upper a-arm bracket? The holes are now above the frame.

Definitely a way to it.

Modifying the stock steering is my intention here.

This can be accomplished a couple ways.

Angle, tubing ....

I was planning on molding the reinforcement into the frame.

Awesome thread and great write up. Curious as to why you go to the newer style crossmember?

Hey Kyle ....

A '63 and UP crossmember does not need to be changed.

I only changed it because I wanted to get rid of the Torsion Bars (60-62), and upgrade to a coil suspension.

Kyle@FTP · 02-07-2014, 10:10 AM

Thanks makes sense now that I think about it. I have a 67 GMC that I will be doing the same thing to. So this was a great thread to run across.

**LostMy65** · 06-01-2014, 12:44 AM

I've been reading lots of threads on Sectioning, Z-Frame, and Notching the Crossmember.
It took me awhile to visualize what is happening with each option, and I really like the Sectioning method the best for one major reason. The Crossmember Notch, and Z'-Frame both raise the motor. Or I should say; lower the body and frame down without lowering the motor in relation to the drop.
But with the Sectioning of the Crossmember, the motor drops along with the frame and body.
For many of us 60-66 guys, this works out better. Because a lot of us running an HEI are already right up against the firewall with the cap. Lowering the body and frame without lowering the motor could cause us some issues with our distributor caps hitting the firewall.

If you move the engine forward. You can solve that issue and create newer ones with possible recessing radiator or going with electric fans. Everything causes some type of issue. Sectioning will cause steering issues. Either way you choose it can be worked out. I'm going to section my xmember without Z.

jjzepplin · 06-06-2014, 08:04 AM

You are right sir. We all become GM engineers at some point in our builds. This site brings all of us together. Not sure I would tackle this. But I'm thinkin about it.

rico12410 · 06-25-2014, 12:16 AM

thank you very much for the write up chief!

**PowerdbyChevy79** · 01-24-2015, 01:50 AM

trying to give this thread some life!!! ..hey chief...did you ever finish the burban..

**ChiefRocka** · 01-24-2015, 03:31 AM

Thanks man ....

Not yet, but it's going pretty good.

**PowerdbyChevy79** · 01-24-2015, 07:55 AM

Cool cant wait to see some pics...
Ok question...is putting a crossmember from a 71 a bolt in and then just transfer all the steering over (a-arms,draglink,pitman,idler arm) and what about the back..i have no experience with torsion bar set up.im buying a 60 panel and i want to drop it...

WEBBY1 · 01-24-2015, 09:20 AM

This thread helped me quite a bit

**Chevy Fleetside** · 01-24-2015, 12:16 PM

Need to take a cruize down to your neck of the woods with Luca some weekend.

More pics are in the actual build thread ....

The crossmember will swap into a 62 and earlier chassis, but you need to redrill some holes.

This is beneficial in centering the wheel in well in dropped applications

Anytime .... im headed to Turlock in a few

doublebeetx · 01-25-2015, 09:37 PM

How does it help in centering the front wheels ?

**ChiefRocka** · 01-25-2015, 10:42 PM

By relocating the crossmember about an 1" forward, it centers the wheels in the fender opening.

This would be in dropped, bagged situations

doublebeetx · 01-25-2015, 11:10 PM

I thought about that, but what do you do about the taper of the frame ? My 64 begins to taper in just ahead of where the crossmember originally bolts in. Sorry to ask too many questions
