Unknown vintage nitro

[TheMidnight Pumpkin 279]

Hello, can you help me identify this vintage nitro?

Also, what year do you think it was made?

note the weird E clip on wheels and clear diff covers  

 Thanks

Does the fuel tank cap say Mantua Model? That's the brand. Late 80s era 1/8th rallycross car.
