73 small block front end rebuild/upgrade

[Texas charger 73]

my 73 front end is pretty worn. i want to rebuild it and or upgrade it. does anyone make an all in one kit? second my k member bushings are worn and cracked(not surprised because they probably original), are they easy to change? how to change? do i have to drop whole k member or can i just do one at a time.. i dont have a lift, barely a floor jack, no engine lift. i dont want to drop motor or tranny. just gonna be a cruiser,not a racer. is there better control arms? torsion bars? or factory one fine with a bushing upgrade.. also $$$ is tight so cheap is what im looking for,but still decent quality

Prothane has a kit for the k-frame isolators, I used this on my 73 RR, its polyurethane. When you change your isolators, make sure you reinstall the metal shims if there are any on your car, usually on the back mounts. Also, you will need good clearance to get them out, as they are metal sleeved, and notched to the hold in the k-frame.

For the rest of the stuff, you can do either polyurethane from a few makers or original rubber from Moog. Just an FYI, I did Moog rubber on the a-arm bushings and lower control arms because none of the polyurethane ones fit properly.


You can get tubular control arms, uppers, not sure about lowers. If your torsion bars are original you may want to think about replacing them.
Good luck, hope this helps.

I got their "small" kit for my 66 in poly-graphite and it went on perfectly, and was very cost effective.
I filled in the other pieces not included in the kit with Moog brand from other sources.

Be aware that polyurethane and poly-graphite are not the same.
Polyurethane is famous for hard to quell squeaking.
Poly-graphite is impregnated with lubricant designed to address the squeaking.

My 73 is the first isolator equipped Mopar I've owned, and I'll say that there is certianly a difference in handling versus my previous 70 and back B bodies. I was looking for solid isolator donuts but it seems they are now somewhat pricey, and I ended up buying a set of urethane ones from a member here.
