Hey everybody , Im 56 y/o Ive Been in law enforcement for 24 years. , I have a 2000 crew cab super duty long bed . it's old and tired and I'm looking at the left over 2017 f-350 and F-250 . I'have been looking on EBAY and I've been to the local dealer here and I did take a few photos of the both rear springs and blocks. I can verify the blocks are the same 3". and that the both truck springs are the same length and that the 250 has three springs two full length and one short. the 350 has 5 springs ,one is the overload it looks like it has the same short spring and one extra full length . I need to know if I buy the 350 can i remove one of the full size springs and just put it back in? or would I have to buy a set of 250 springs . I will photo the rear ends tomorrow just to be sure of what I'm getting . Lastly and most importantly I need to know if the front springs and shocks on the 350 are stiffer or are the same . I don't need a 350 or a 250 for that matter I just like them more and I'm a big guy. also I think they are a much better value than a loaded up 150 the price ends up very. I found a brand new 350 4wd Rudy Rey Black Leather, 6.7 PS Lariat ultimate package , Navigation , moonroof, chrome Package, sprayed bed liner and step 6 switches back up camera ect ect for $ 61,000 or make offer. I think its a good Price do you? they do have 699 handling fees and 800 shipping its in Kansas. Any help would be great.
