So...did you bend the rear bar to be narrower to get it to fit? 70 318 Chally vert FC7/XW (sold) 06 300c SRT8 04 2500 QCLB 4x4 HO 1971 BMW 2800CS 1955 Nomad 1970 280SL

Larry I agree, appears to be a modified 72' plate, possibly to fit the 73' and later spring isolator mount. 1972 Road Runner GTX 440 6bbl 5-speed [img]http://72rrgtx.com/carpics/bucket/DSC06730r-1.jpg[/img]

If you want to increase the roll rate with the existing springs you can increase the leaf spring bushing stiffness. Alternately increasing spring rate will also increase roll rate.

I was kicking around the idea of a rear sway to help with street handling not track... As for first Q, Firm Feel has a nice rear bar kit that is frame-mounted vs. axle mounted so there's less unsprung weight. I know there's a kit for 3rd gen B-Body, not sure about '69 B-body though. Might not work with some aftermarket rear disc brake setups. www.firmfeel.com. As for 2nd Q, can't say... (Or '70, sorry...) Last edited by MoparMarq; 03/25/10 08:17 PM.

Maybe just cop cars. I've seen plenty of them in '71 and I have 2 '72 with rear bars one is a 72 RR with Gtx package and another is a SSP 400 4spd. Both factory... Locating holes for the anchor bracket bolts are present on 71' b-body frame rails making retrofit of the 72' and later rear bars very easy. Likely, there are/have been many 71's running around with rear bars, fact remains for 71' the factory never offered a rear bar factory installed on the b-body, with the possible exception of a special order Police package. "72 RR with Gtx package"? There wasn't a "GTX" package or option offered in 72', any U or V coded 72' Road Runners were renamed "Road Runner GTX". Sorry for not writing the exact terminology for a 72 and writing "package"..But your wrong it was an engine option so your wrong too I guess cause with the "option" of picking a U or V code it was then a RRGTX...Some things that I have seen come with that "engine option" were torque boxes and a skidplate on the K-member...

But basically it looks like rear bars were fairly rare until the early 70's on B body cars and even later on the A body cars.

They began its life like the ones 72roadrunnergtx attached and noticed right why the mod was made. I tried to modify to fit on an iso clamp assembly ( pic is mine ). I got those trusting on seller being the correct ones for my car ( without pics )... they weren't. Being outside USA and they didn't exist down here I tried to make them fit somehow. I enlarged the holes and welded shims to fill the step on iso clamps... here is another view showing the welding deal: 5895840-P10500941.JPG (189 downloads) With a Charger born in Chrysler assembly plant in Valencia, Venezuela

That was what made to take the conclusion the axle pedestals are shorter on 73/74 than 71/72.... and even some ppl said I'm wrong about, geometry doesn't fail, and I'm still practically sure of that although never compaired axle pedestals side by side. If wasn't for that, they were to work! At the end had to buy another ones, this time the correct ones WITH PICS! With a Charger born in Chrysler assembly plant in Valencia, Venezuela

I don't know about 72 318 cars, but 73's got the bar no matter what engine the car came with...as long as the Rallye/Cuda package was ordered.
