5.3 Vortex 4L60 E transmission into 72GMC Jimmy question

[David623]

To those who have done this engine swap, I have a question about the motor location. Right now I am using the stock transmission cross member location and I have an Advance Adapter motor mounts that I just drilled into position. The stock drive shafts, front and rear seam perfect fit, but the engine seems too close to the firewall. I don't have a problem with redoing the stock drive shafts to give better clearance from the firewall, just trying to figure out if this is necessary.
