Leaf spring bushings

[mopardog]

I am needing to replace the leaf spring bushings on my '72 Road Runner (big block 8.75 rear end) and was wondering if anyone could tell me which ones to get as far as diameter etc. Really could use some help. Thanks

These are what you need for the rear: http://www.summitracing.com/parts/ptp-4-802-bl?seid=srese1&gclid=CLTCnfHf2MgCFZUWHwod9B8KnA

The front bushings usually come with the springs, but they are the same for the 72 and older springs.
