I have used Afco shocks for sale that are in good shape.  They have Dyno sheets and are 6 inches. 
I have the following:

• two 2/2's
• one 1/.5
• one 2/1
• one 1/3
• one 3.5/4

At the first of the week I have thick radiators for 600s and 1200s and inline water heaters coming.  There will be other parts coming soon.

Call or e-mail me if interested.

What are the dimensions on the 600 radiator and how much?

the dimensions are the exact same as a stock PMP radiator, but it is double the thickness.  Call me for more info.  John - - 360 661 2643

I also have radiators for 1200s.  The dimensions are 18" wide x 12.5" tall and 3" thick.  Call for price.  John-- 360 661 2643
