auto crossmember help

[Leroy-B1]

so I have a 60 apache and I am using the original frame...I did a front stub and rear end swap from a 85 Silverado to get 5 lug and disc brakes....so now I am at the point of installing my motor and tranny...I was wondering what you guys used for the transmission cross member in the x frame and if anyone had pics .....also looking for some help on where the crossmember needs to be...going with 327 and a 700r4 using the 85 engine mounts on the frame...any help would be great
