Just reviewed my post and suggestion and, yup, I did make no mention of RPO F41, which is actually a suspension package that includes the progressively wound springs, braces for the front suspension, front and rear anti-sway bars and a few other bits and pieces, according to the component break out. The picture that I used was the closest to what currently resides under my 85 SS and which came with the car, along with the front and back sway bars and the lower front braces and the other. if you are asking is all this the true F41 package, I can't say for certain simply because when the car came to me, the original trunk lid was both damaged and badly rusted underneath the spoiler and it ended up getting replaced with an LS lid from the same year. Highly likely that the option list that would have been stuck to the underside went with the old lid to the crusher, probably somewhere around 2005. Still, I could have pealed it and transferred it over so might take a look-see tomorrow. The choice of the Dixie part was quite random on my part; Eaton offers a coil package as well.
