towing concerns with 3-link bagged suspension
i am building a '59 chevy truck. it started life as a 3/4 ton truck, while i don't want/need to keep the payload capacity, but i do plan to tow with it. it will have 12" discs front and rear, so brakes are not a problem.
i want it to be able to tow my mustang (3,000 lbs. + trailer), and possibly my lightning (5,000 lbs. + trailer) to the track, and i was wondering how you would rate the the load capacity of a 3-link suspension with bags. i have designed the 3-link as far as lengths and angles are concerned, and i will be building it myself (no off-the-shelf kit). i assume i would just need to calculate the vehicle weight including the loaded trailer.
how do i calculate the diameter and thickness that the links need to be to hold up?
i have an 8.5" 10-bolt rear end i am using in it, would that be strong enough?
do i just need to over-build everything to withstand the extra weight?
