I'm planning a suicide front end for my rat but have no idea how to choose the front spring. I want a posi super slide reverse eye spring but when i use the chart to determine spring length in the speedway catalog it says i need a 34 inch spring. i have a 37-41 i beam axle dropped 4 inches by sid at droppedaxles.com and plan to split the 41 wishbone and mount the spring off it like donsrods did his.

i'm thinking the posi 580-2040 is the one i need since it recommends axle 2860 which is a superbell 4'' drop i beam with 38 1/2'' perch centers which is basically what i have.

any tips or tricks i need to know before i order one or am i on the right path?
 
start mocking stuff up..

get your axle, and bones together, then throw on the pivots(perches) and measure the distance between them..

no sense in sending back a part becuse of premature measurements
