Im going to put my SE trans in tommorow... on the frame of the car, there are 2 pairs of bolt holes for the crossmember and I don't remember which ones were used originally. does it matter which ones i use? the car is an 83 that is going to have a 13B. TIA.

 

that crossmember will only go on one way. shouldn't be an issue.

 

there are 2 studs for the crossmember to attach it to the body, one on each side. therefore you only need one bolt hole on each side...instead there are 2 on each side. its been a while since i took out the original trans so i dont remember what it was like before. not sure why there are extra holes, maybe a universal thing during manufacturing - 12A cars use one set and 13B ones use the other....?

 

theres only one way to install the crossmember it should a stright forward swap
