C-body leaf spring replacement

[Frank]

Is the leaf spring length for C-bodies the same as for other RWD applications?

I have '70 Newport with original 2.5" 6-leaf springs. The are tired, and I would like new 7-leaf springs. Finding the swap information is quite difficult. Finding a vendor is hard too.

Can anybody recommend a source for new springs? I know about Eaton, but am hoping for something easier.

Look in your phone book under springs - automotive. Take your car to the shop of your choice and they will make up a set for you, or (more likely) will re-spring (re-arch) your existing set and add a new (extra) leaf too. Probably get new shackles, bushings, etc.

If your car is not drivable, or if you have already dismantled the rear axle, then just take the springs to the shop and again have then re-sprung and get the extra leaf, then take them home and re-assemble. Get new shackles / bushings (urethane?) from Year One or Just Suspension.

B body springs measure 22" front and 36" rear from the spring center bolt! C bodies had 25" or 27" and 34 to 36" rear. You have a couple options. The easiest and cheapest is to add a full length spring to your stack. You can go to your local spring place (truck spring places do cars too!) and have them cut a spring the size and length you want drilling hole to your spec. (or get a wrecking yard one) Buy the centering bolt and spring clamps from them too and install it yourself. (they will make nee U bolts to custom if you need them!)

Simply jack car up and support under frame ahead of front spring perches, remove wheels, cut any spring clamps off and undue the U bolts. Axle will lay on top of main spring! You can undue the centering bolt or cut it, springs come apart. Add leaf and pull together with new centering bolt. Cut off access and reinstall everything. Do other side. Or take it to spring place (yellow pages) and have them re arc existing and add leaf and replace any worn bushings!!! Most can build new spring sets too!!!!! Check you local spring guys and price quotes first!!!
