Brake Light Switch - Sorry Lucas

Sorry Mr. Lucas, but after we were black-flagged and lost 2 hours during last years Charlotte Motor Speedway race because the MGB brake light switch was crappy, we've replaced you with a higher quality switch from a Datsun 240Z, part number GO300, from eBay for $7.50.

I noticed the pedal arm has some play side-to-side, so I installed the switch at a slight angle; turns out it would not have made a difference but there you go; it's just the price of being gormless.

Here it is installed, with the brake pedal NOT engaged :

Here with the brake pedal partially pushed in:

Here it is installed on the Brake Pedal Box. More Tea, Vicor?

Windshield wipers... well maybe not


Removed the plexiglass windshield (eg scratch collector) that we had so much trouble with (eg couldn't see through) in the rain at Charlotte Motor Speedway last year (eg Black Flagged for passing under Yellow that we couldn't see).

Drilled out the rivets and removed the remaining screws (eg 25% of the screws have been lost to vibration over time). While it was out I stripped down any surface rust (eg it's English) and coated them with De-Ruster treatment.

You can see the red Kill Switch that I will be moving to the center of the dash (as per ChumpCar Rules [.pdf]) while the windshield is still out.


The big item that was planned to do while the windshield was out: adding some Windshield Wipers! I had scavenged a system from Crazy Rays last fall and had been waiting impatiently to install them.

Finally get to it and.... can't be done as is.

The roll bar, eg the excessively over-engineered roll bar, is in the way. The photo to the left is a shot from inside the car looking forward. The farthest blue bar is completely unnecessary for LeMons, ChumpCar, and probably VRG, SCCA, NASA, and pretty much anything else except a Sherman Tank Demolition Derby. Never-the-less, I can't bring myself to remove the extra pieces; after all I've hoodwinked talked my friends & family into racing this beastie and therefore the more safety qualified the car is the better. Who cares if it doubles the weight of the car?

Sigh.

So, options at this point seem to be:
  1. Cut out extra roll bar bits (don't wanna!)
  2. Install some other after market wipers, possibly a single one on driver side only
  3. Install the MGB wipers, but from above the windshield! Top rollbar may be in the way :-(
  4. Drive without wipers; since we now have a GLASS windshield we can use Rain-X and it may be ok. :-(
  5. Do a 1968 American Rambler wiper system eg twine and clothes hangers manually operated
  6. Rig up a few hairdryers on the hood pointed at the windshield (this is LeMons after all)
  7. Hire a Baltimore street corner window wash guy to sit on hood during race
  8. <Your suggestion here; please leave comment below.>
