Hey Cheif,
I know exactly which one you are looking for,that was hand made fiberglass,some guy up in Canada,I had emailed him and found out all he would take was certified or cashiers checks,I had to think on it a while and by the time I decided to get one poof he's gone,tried to email him several times with no answer,shame as the panel in his add was pretty cool looking,I hate to be the bearer of bad news but there it is,I ended up making a sheetmetal panel that fits inside the dash and replaces the stock speedo panel,it's not really that hard just a bit tedious and time consuming,I got the idea on here,I think 383bu may be the one I copied (loosly) off of,If you stop back by I'll try to post some pics,Havn't experimented with that too much as of yet,Later,
