Model B frame questions

[Uncle Bob]

Okay, so a little time opened up this morning and more pieces of the puzzle to present.

Here are a few pics of the front cross member. Note the uniformity of the bolts mentioned as well as the spacer at the bottom, that's typical of the other three. You can see multiple welds across the top. The previous mentioned motor mount area doesn't appear flat, but rather has some, what I would call elevated pads, one side with a bit of a cobby weld. Not being real familiar with stock versions of these I'm at your tender mercies on those. And just for grins there's a shot of the rear member hokey install including at no extra charge some "farm boy" reinforcement.
