Among many different mods I'm in the process of,  there has been one I really want to do,  but it is far beyond my skill set.   I think I've gotten the ability to have my university's metal shop work on my bike as part of their hours needed spent in the shop and all I have to do is pay for parts.  This make the very unlikely mod which at any regular shop would cost a lot more than I've got,  a very possibly thing.   I've seen a few great posts on here where it's been done,  but would like if possible some detail as to what the best way to do this would be.   Currently I have the stock seat setup but want to do a bratstyle / cafe  look so I will probably be also making a conversion to a flat bench style seat.   I know I'll need mounting points welded on,  but where and what type of shock and how to know the best place for the right performance,  etc...   Any help would be appreciated.
