Bars are Skull Skates repro 26" Cruiser bars. You need a shim to fit them into the Ashtabula stem. Fitting is a nerve wracking experience, although the cross brace is much narrower than the main part of the bars, it still needed the stem opening up. Take care and give it a little heat before inserting a small pry bar in the slot. Just bend enough to get the bars in and then quickly close the gap before it cools. Be carefull when closing to ensure the bolt holes are aligned. You only get one shot at this and those Ashtabulas are getting scarce.
How is your project coming along J? Why don't you start a thread over here- help get the UK Klunker scene going??
Cheers
