Super six van

So I was wrong about the b100. There is a clutch pedal. The clutch pedal is not hooked up to the tranny tho. Should have it home tomorrow. Might see what I can do to get it running. If it runs better Tha. What's in the dart then I'm gonna a pull it asap and tear the darts motor apart.
The rear end is oval with 10 bolts. By the pics online it looks like an 8 1/4. I measured from drum to Dru. And got 58". The dart has a 7 1/4 and measures about 52". Tires look like they could go out a bit more and the 3" extra looks like it would make a decent fit. What do you think.
Will the air cleaner not fit under my hood for the super six from the van? What about the brake proportioning valve can I use the vans?
