Still a douchey place turning into fsc!
Pirate will never be FSC lol.
OP:
Any SAS is going to be costly, not only in a monetary sense but also in hours, days, maybe even months of work. There is no "best axle" answer, like previously mentioned it really depends on what you would like to achieve, what you're willing to spend, and how mechanically apt you are. There are so many options/ variables it's not even funny. If someone were to write a book on SAS swaps and include all the options & variations it would rival the bible (except this SAS book would hopefully be proven facts, but we'll save that argument for a later date :crazy
I work next to a few of the best fabricators in the states in my opinion. I've had thoughts of a SAS for my HD. Hell, I even own all the brackets, tubing & joints to pull off a radius arm super duty axle under my truck but haven't started due to having a pretty good idea of what is involved in a swap like that.
Do some more research, Pirate has a TON of great info but it will take some searching, some reading, and some thought. Ask detailed specific questions and you will get detailed specific answers. If you ask questions like the one above, you will get answers along the lines of " If you have to ask....". I'm not here to add to the fire, just to try and help, I personally love seeing all the SAS Chevy projects, it gives me more ideas :up:
I will say one last thing. It will probably never be perfect and it will probably never be completely done. There is always something to re-work, or something that can be made better down the road that you might have overlooked in the initial design process. If you are willing to keep devoting the time and $$$$ to work out the kinks after the axle is sitting under there then dive in headfirst and I'm sure the support you are looking for will be there considering you ask the right questions.
Cheers.
