38 mm carbs need guidance on choosing a throttle housing

[boardwine62]

I got my bobber running and my biggest challenge to riding it by my 50th birthday next weekend is ordering the right throttle. I ordered the standard 77 non special cable and need a plain (no switches) throttle tube and housing. Any help for this new bobber rider and AARP member to be would be great!
Thanks, Roger in VA

I am guessing you are running 7/8" bars. If so, this throttle works well and is all metal http://www.lowbrowcustoms.com/index.php?l=product_detail&p=2043
You can find them on ebay as well.
