Analyzing the Le Mans Mini Marcos (3)

Unfortunately, just about all of the mechanicals of the Le Mans Mini Marcos have disappeared, but there are still some signature marks that have been saved. The fuel tank, the pedal box and the pick-up points where the roll bar was attached to the car's body shell. Let's have a look at them.

This is the fuel tank in its position. Hrubon said he made it himself and it could carry 80 litres of petrol

And this is what it looks like when you take it out. The base definitely is from a Mini Van, but the top?

The filler opening is huge, 120 millimeters in diameter - I can easily put my wrist in it
Inside it has wash plates to keep the fuel in balance in corners

The same tank is good visible in this shot, taken of the car in the Le Mans pit lane in '66

And again, on the same spot in that memorable summer of 1966

This detail shows the thing even better. The photograph was taken in 1975 when the car had been painted maroon and road registered. Note that the exhaust pipe is now relocated to the rear of the car. It had a side pipe at Le Mans. Roll bar also good visible

Here you see the tank again, plus the cut out left overs of the roll bar on the floor, where it was moulded into the fibreglass. The diameter of the frame is 35 millimeters. Not today's standard!

Detail shot of one of the four cut pout points in the fiberglass. I guess this was a factory option, 
so there have to be more Mini Marcoses with a similar cage. More info is welcome

This is certainly not the best quality image I have of the car, but the roll bar is very good visible 
thanks to the white background of the Dunlop sign behind

And that's the adjustable pedal box! Clearly home-made and very simple, but it may well have
 been effective. Perhaps due to the size difference of the two drivers Ballot-Lena and Marnat?

  1. On the pedal box, have the shortened the throw of the break pedal ?

  2. Like Neil says; the brake pedal doesn't have the rounded end where the master is attached. I can't see how you would adjust this set. Do you suggest the pedals are lowered by one bolthole? Perhaps the rules didn't allow the pedals to be rewelded after alteration. I've found the brake pedal really close to the tunnel on Rikards 69 mk3. And this pedal is 5 mm closer. Great stuff!
