Okay im sorry about all these questions. I hope this question will be the last one. On the screw that goes through the diff there is a washer with a groove all the way. I think i lost one of them (there is two) can i use a regular washer or can i only use a grooved washer? Man god doesnt like me!
The parts i need is not in stock at modelsport
the kit is sitting om the table and i have absolutely nothing to do!
