Rear leaf spring number help?
My truck has spring # 2c34 CA it also has rpn 1592 stamped on it, I was given spring number 5c34 FE also with rpn 0995 stamped on it. The guy was not sure if they came off a 250 or 350 and did not know what year. but they are new. I have searched like crazy and find nothing concrete, Can someone tell me if there is a differece in these springs other than the year of truck they came off of? the second set listed appears to be a heavier duty spring but it may just be that the ones off my 02 have goten soft over the years. Thanks in advance for any help.
