Identifying a springer front end from the 70’s and early 80’s can be a frustrating endeavor. There were so many different manufacturers that came and went that it’s almost impossible to keep track of all the different models that were out there. There are the big boys of course - like Amen and Paughco that are pretty well known. There are also the revered builders who churned out some beautiful front ends - Harmon, Sugar Bear, Finch and Denver’s come to mind. But then there are all the other springers out there, that - unless you were around at the time and remember the ads they may have had in Street Chopper or Easy Rider - can be hard to identify. Not too long ago I stumbled upon this page that has started to catalog some of the old ads. While it’s in no way complete, it’s definitely a good starting point. I’m not sure if the guy who built the page is still updating it or not, but I do hope he continues to ad too it as it’s a great resource.

I’ve also included some picks below of a kick ass Finch springer on a CB750 Chop. I passed on a chance to pick up a Finch springer at a great price a while back and I still kick myself a little bit about that.
