1969 Chevelle L78 Monaco Orange

air bags worked well back then also. Some 50/50 shocks too.

The no-hop Lakewoods do not require drilling - they are bolted on as can be seen in the photo above. Another thing you can try is to change your rear bushings to polyurethane to minimize flex (not period correct though).

With street tires.... I used a set of QA1 12 position adjustable shocks. I painted them black so they're not a noticable. That eliminated all wheelhop. When I switched to Mickey Thompson ET Street tires.....the wheelhop came back.

The bottom line it the upper control arms MUST be higher on the rearend then the body.

Hope that helps, Kurt

I would think an aluminum bushing would be an acceptable vintage option. The Lakewood bars I bought did require drilling the webbing. Checked the online instructions- note #8

I think even if you just tried to pinch the webbing, it would damage it similarly enough or more than the drilled hole.

As I understand it, the grippier that the tires are the further back the instant center needs to be (or the higher the rear contol arms need to be attached).

----Sam,,,Instant center ideally should be app. right under the drivers seat to under his feet. Using the 70 Chevelle as an example, there actually is no instant center as the cars are delivered. The upper arms actually angle away from the lower, longer arms. Thats why theres tire hop. Hop-stop bars reorient the upper bars rear pivot point on the pumpkin upward to gain an instant center. Install them and hop should go away. Other stuff can probably mitigate wheel hop (air bags, etc.) but I think they are bandaids. If someone really wants to race with GMs midsize rear suspension, drill the holes. They can always get patched. Or get another housing. Really good 60 foots are out there waiting......Bill S

The Ram Air IV Gto from Harrisburg that was raced just had the air bags inside the springs.

Thanks Bill. I did not know that the uppers and lowers actually diverge. I guess you would know a thing or two about racing 70 A bodies (LS6s to boot). [img]<<GRAEMLIN_URL>>/wink.gif[/img]


Good to see you at the show Bill!

Here are some more pictures of Jerry's car.



The original &quot;BA&quot; master cylinder.





Factory runs.....





No black tail panel so Jerry did his own lace paint. There are 2 extra holes for the Dickhoff dealer emblem....which he still has.



If you look you can see a screw in the lower left corner of the body panel where the tail light goes. They messed the tail light up and used a screw to &quot;repair&quot; it.







Factory 6000 RPM tach.
