I will be swapping out my TPI and installing a LS1 and T56. I was just wondering what your opinions are for the best K-member and trans cross member

for the price I have been really thinking about the spohn ls1 swap k-member with no bracing just mild steel.

the trans mount seems like the only way is custom (which is what I did myself) other wise the spohn unit has header and other clearance issues-(from what I read??) and it seems drews trans mount is hard have made now days.

right now I am using the factory k-member with the spohn motor mounts, and my custom double hump trans mount.
