For the drag strip uneducated what class, geographical region, sanctioning body is this happening in??
That's a front side no prep race in Pageland, SC. Turbo John lent Nick from Hustlin' Horsepower his fox body, and Nick put a solid front axle under it while he was borrowing the car. None of these really have sanctioning bodies, with a few exceptions they're local promoters.
The mustang in the pic was a roller and loaned to a racer who'd wrecked his car. He used the front suspension and drivetrain from his wrecked car to Frankenstein something just so he could continue to race. Just saying, it wasn't really done like this on purpose.
I really wish they'd implement a rule that the car has to have a front end on it. Some races have. I enjoy watching the no prep stuff sometimes, but don't think I'll ever try it myself.
