1967 Dart transmission crossmember

67-69 only the bolt are 1/2 13
70 -76 the bolts are 3/8 18

using the smaller bolt cross member on your 67 will fit but the trans will hang lower. Just some info you may consider. I may have the one pictured mint with bolts 40 + ride trans mount bolts and square washers included. I am keeping the other for my car
