Three-link, need some suggestions

[Randy67]

I did a 3-link for my 67 el camino and I found out a few things along the way. My car isn't running yet so I can't say how it works yet, hopefully in 3 months I will know more.

1. The angle of the rear shocks limits the length of the panhard bar. I have a 36" bar but could have had it as long as 40-42" if the shock wasn't in the way. The bar isn't straight across as viewed from above, since the shocks required the frame mount to be about 2" farther back than I wanted. Or a longer mount is needed on the frame, I used a stock car mount to save fab time. A Watts link would probably be a better idea, since the shocks wouldn't affect it as much if the center is frame mounted and not on the rear axle.



2. I used the stock crossmember for the 3rd link, but did brace it quite a bit. Still, it would be better to make a stronger crossmember.

3. With the 3rd link center mounted (and not wanting to cut up the floors) the adjustment are limited. The pinion yoke gets close to the crossmember when the suspension is compressed and the floor is right above the crossmember. El caminos have less floor space above the axle as well (chevelles have more room, not sure how much more) so I had to put the link right above the diff housing. If you are willing to cut more out, you will have more adjustment options. Or you could just have the 3rd link offset to the pass side.

4. I was able to run tailpipes, but el caminos have the fuel tank 6-8" farther back than a chevelle, so you may not be able to run tailpipes. My tailpipes run over the axle and the panhard bar/brace and then drop down. Side exit exhaust would be an option.

Hope some of this helps.
