The parts are out there. Like restoring anything, you just have to be patient and be willing to pony up for the right part. Occasionally you get lucky but it's a rarity.
BTW... I'm currently restoring a pair of old LRV's. Their pictures are below. Great old bikes and just like the one I had as a kid.
Still trying to figure out what to do with this. Might just leave it as is and build it. One of the few examples of the Blue epoxy over chrome LRV's I have ever seen. The finish is rough and abused, and I'm tempted to powder coat it. However, given it is the only one I've ever seen that might be stupid regardless of how beat up it is.
The chrome LRV and the Parts to date. This one's in almost perfect condition aside from the dropouts where the wheel was mounted. There is no pitting, rust or flaking of the chrome. Easily a 9 out of 10.
And Finally my original LRV circa 1979
Great Bikes!
Would love to see what you're restoring...
