Front crossmember problem help?

[jkw]

Hey guys I've got a coil sprung 99 2wd Mazda b3000 roller that I bought on an impulse as a side project while I work on my 97 SAS n v8 toy. The problem is the last guy pulled the motor and there's no holes in the front crossmember for the motor mounts. I looked at a frame in the junkyard and it looks like there is a piece of square tube riveted on each side of the crossmember that the mounts attach to. Any idea how I can replace these or build new ones? Appreciate any help

The mounts bolt to the cross member well into the coil spring towers -- gotta pull the front coils out to get to the lower nuts.
