Been lurking a long time...finally have something to post....71 chevy stepside

[mustang347]

so i have had this truck since i was 16 which is 32 years now. It was my daily in high school and how i learned about motors and racing. Before i received the truck it was my grandfathers and was used on his farm. the last time i drove it was 2005 and it has been sitting in my yard ever since. My son just turned 13 and i am using him as an excuse to put this truck back on the road. Now this will be a long project but i have a pretty good start on it. I was about to order a belltech lowering kit then i found the "grand slam" on CPP's website and am thinking about going that route. Please let me know if anyone has any experience with this kit or if there are other options i should look at. Thanks in advance.
