Lambretta Gear Box Endplate Fastener Kit - MBP0212K
We recommend using this set of high tensile bolts to secure your gearbox end plate. Yes, in theory you should use studs in aluminum but as long as your threads are OK then these bolts will be fine. You use more of the thread when you use these bolts so your end plate is better attached. You gain more surface area by only using a plain washer, always use a small amount of loctite on the threads.
