From very vague memory, so I'm probably wrong, front spoiler and steering rack come to mind?

From the Tuckey book:
"...The UK-built car had a softer spring and damper setup than the Perkins Commodore, and was using UK-built front uprights and their own rear axle with aluminum uprights....
....The Perkins cars (10 and 40) used his Harrop-built braking system, the TWR car an AP-designed system."
Basically Walkinshaw had his own ideas on how to set up a Commodore (as per the above, plus brake pads, tyres, ride-height), despite there being 8 years of data available through PE.
As for who blew up Larry's engine:
"Walkinshaw got into the Larry Perkins Commodore at precisely 2.24 pm"
"At 3.48 it was Walkinshaw in to give the car to Perkins for the run home" (in second place)
"Meanwhile, Perkins was being unmerciful with his Commodore....he was hammering in 23-24's...But on lap 132 he was suddenly six seconds slower..."
"The oil pump drive had broken and a rocker arm had gone...The engine had lost oil pressure, and the crew changed the oil pump, but when it re-started they couldn't get a decent reading, so they decide to call it a day."
And then there's Larry retrospective analysis of it all on Youtube:
