Straight axle wheel alinement question

Im using a 59 ford P U sraight axle under a T bucket type scratch built car and want to know if I should aline it to the axle specs for a 59 ford or is there a set of specs for this type of car? the car is a glass over steal tubing ( 25 Dodge) T bucket that will weigh as close as I can guestimate about 1600 pounds. wheel base is 112 inches and is of course heavy forward of the fire wall - coil springs up frt with 1 1/2 inches of travel. Any input would help alot

 

Put about 6-7 degrees of caster in it and set the toe -in at 1/8 for bias ply and 1/16 for radials

 

thankyou andy - that will help at the shop

 

good, i had guessed at mine cause i couldnt get the correct answer on caster

but one question i have is in all the years af wrenching and doing alignments wouldnt you want a little toe out, toe in is usually for FWD cars cause of the torque issue??????????

 

I believe that FWD cars are set toe out because the thrust tends to push them forward thus toeing them in. A rear wheel drive has rolling drag which toes them back out
