Thanks Sasza79. I will check l it out. Its winter here, so trying to get the parts I need to install in March or maybe February.  

Question on the trailing arms bushings.  Once the trailing arms are out, are the bushings hard to remove and replace like the A arm bushings, or do they just come out and new ones put in?

Well, After doing a few, my own, and others, let's just say they are NOT a take and replace project.

Thanks for the help. Just getting ducks in row so when I start this project In a month or when weather gets a bit warmer here.

I will be doing mine soon on my '79 C3.   I already have my trailing arms removed.  I will update and let you know how it works out.  I will be removing the original OEM rubber bushings, and  I will install the replacement red poly-bushings made by Energy Suspension.  

 I haven't pulled the trailer arms out yet. But found a video on you tube for taking out bushings , which looks simple enough. It doesn't have a title except for 002 under its video picture. its by Greg  Ballenger.  Came across it looking how to remove trailer arm bushings 69 corvette. If i can figure how to send the link i will. 

Try Greg Ballenger002.  the video should come up on You Tube

has anyone used Por -15 paint. Thinking of using this after sanding down rear trailer arm and frame where i can reach. Thanks

That is funny you ask...I am planning to use Gloss Black POR-15 on mine.   You can see a good review comparing it to other coatings, the presenter is 'ProjectFarm' on YouTube.   He thoroughly tests all kinds of tools and products!

I think poly would be great for the trailing arms, but don't use them on the strut rods.  They won't let the strut rod twist slightly as the trailing arm goes up and down.

I'm going to stick with rubber bushings for my trailing arms and just buy the tool for installation of them. Then sand them and use the Por-15 to paint them.
