I'm building an m416 trailer to tow behind my truck. I just ordered a new axle with electronic brakes and need new leaf springs. The orignal 416 leafs i have are warped really bad. Im looking for something that is 36 inches eye to eye because thats what the orignal springs measure too. Im also looking for something a little softer then the factor springs. If anyone knows where to buy what im looking for a little help would be great.
