I have a few body mount bushings that are cracked, how hard are they to change? And are the poly ones any better then the rubber ones?

I did mine on my old 89 C 15 00 not a bad job but I had to put plates in where the mount went on cab. They were rotted. Poly definitely better than rubber.

If you can get the carpet pulled up and spray the top of the bolts a week in advance it will help.
Like Spiderjohn mentioned it is common for the metal mounts to be rusted and need a plate added or a large washer
Its not a bad job as long as everything goes good and no body bolts give you a problem. Loosen all the bolts off first, then pull the bolts from one side, jack up and remove the old mounts and replace with new ones and then put the bolts back in leaving them loose and do the other side.
I've had the poly body mount bushings in my 92 now since 2007 and no complaints or problems.

I need to do the ones on my 72 K5, I bought new poly ones but just haven't had the time to put them in.

+1 on rust...if they don't give you a problem, should be an easy job.  Soaking in PB is a good start!

 

For body mount, rubber or poly should work.  I like poly on suspension, but am indifferent on body mounts.

reason I went with poly is the fact that they wont wear down as fast as rubber. but its just my personal preference
