Overblown. The percentage of 7 bolts that did walk is quote low, but it became quite the meme.  That said, I only ever built/drove 1g cars with 4 bolt rears, so my failures were limited to stretched head studs under big boost.
		
		
	 
 I helped build one at a shop that suffered that problem twice.
Otherwise, only messed with the 1Gs myself.
Had a 92 Talon TSI AWD with a hybrid t3/t4 deal.  6 bolt crank, 4 bolt rear, new transfer case from Eagle.
Popped a head gasket and down the road it went.  LOL.
Oh to be stupid and 20 again
