Firstly, there were 3 Group 'A' homologation specification of chassis used in Europe, according to the pictures above.
VK Brock - Homologated by Brock/HDT with 5L engine, carburettored
VL Brock - Homologated by Brock/HDT with 5L engine, carburettored
VL TWR/HSV - Homologated by TWR/HSV with 5L engine, fuel injected
From the cars that ran in the 1986 ETCC campaign, there were 3 chassis that made it to Europe.
2x HDT cars - the #5 VK at Donington with Moffat/Brock at the wheel is the same chassis as the #6 VK at Spa for Bowkett/Lowr/Baigent.
HDT brought over a new chassis for #5 VK for the Spa 24hr enduro for Moffat/Brock/Harvey...
Where these ended up is not totally clear....
1x Roadways car - the #27 VK for Grice/Bailey/Delcourt/Others.... was the same chassis that went thru the entire European campaign for Mr Small's team, rebuilt and updated with new bits developed locally in Australia during the year (and after the crashes...
)
It was always thought this car stayed in Europe but where and how is not known
For the 1987 WTCC series, there were 2 VLs that made it to Europe.
VL Brock - #5 Rothmans Mofffat/Harvey/Mulvihill car was an ex-HDT chassis, sold to the Moffat equipe when HDT could not afford to run it locally after splitting with Holden.
This chassis is in Melbourne, still in Rothmans colours, owned by a collector
VL Brock - #3 Mobil Brock/Parsons/Crichton car was an HDT chassis (rumoured to be an updated VK) which only did Spa '87... till the engine broke anyway.
This car made it back to Melbourne, and was the team's spare for the domestic series that year.
A change from VK Brock to VL Brock to VL TWR/HSV was not impossible with the right bits and pieces, all available from Mr Small's Roadways equipe at the time. The biggest cost of an upgrade to VL TWR/HSV was the need for the fuel injected engine (with its 4 bolt mains, mega aero kit that added serious weight, and the beginning of input from Happy Tom) as this was a black art not quite perfected down here in 1988....
