My leaf springs are the double eye type, that are not fully closed at the<br />end like the letter "C", can I use the double eye leaf spring that are<br />fully closed like the letter "O"?<br /><br />Where is the best place to buy them?
Sure,if you can find a set of the correct measurment between eye's. Measure carefully between eye(or bolt)centers.Using the same spring type as original is preferred but closed eye's are ok as long as you get the correct capacity.Take a look at NorthernTool.com.Be careful selecting springs,most are rated(weight capacity) as pairs(2),instead of each.Good luck. 
<br /> I stand corrected.JB is right.You will need spring shackles on non-slip springs.Sorry,was not thinking....
