I was able to find out that your 2007 Weekend Warrior model CR3905 is triple axle trailer with a GVWR of 16k. That means for each axle you'd need a capacity of at least 5,333 lbs. Which means you most likely have 6k axles. We have a few options for that capacity for leaf springs but you'll need to measure the length of your current springs to be sure.

If you have 26 inch long springs you'd need part # e94SR.
If you have 25-1/4 inch long springs you'd need part # e78SR.

You should note that old springs stretch a bit over time so factor in that your current ones probably stretched around 1/2 inch possibly.

For bolts we have the part # 166081 which is a bolt that comes with a nut.

2011 Eclipse Stellar 5th wheel toy hauler – 3 axle wide body - the used springs measure 26" but i dont know what the factory length was.... they are a 4 pack spring... i cant find that in a 26 inch... I can however find it in a 6 pack.... how do you find out what the original size was ?

While it is possible for leaf springs to stretch over time, there isn't a consistent way to determine what the original length was since there are a variety of factors that come into play (load of the trailer and how far it has traveled just to name a few). Basically you just want to ensure that your leaf spring doesn't have any pressure on it prior to measuring and then choose a replacement that has the same weight rating and as close to the same center-eye measurements that you were able to find. If you can only find replacements with slightly less length then those should still do just fine.
