With in the next month I plan to install a 4" SPOA Kit in my 88 Sammi. I got the printed instructions and have read them several times over. I also printed and read the instructions off this web site about SPOA installation. Looked at the pictures and have a good understanding of the task at hand. What I would like to know from all you smart guys that have done this before is What problems I may encounter and What things I need to watch for? Experience is the best teacher.
