Used one for my T9 conversion ... it fitted without any adaption ... had a problem with it and returned it to Burton last September ... still awaiting it's return.... Speedograph posted it back to Burton before xmas (accepting their word that is) and blamed postal delay (or now probably postal loss) ... sent untracked .... Burton are very apologetic and trying hard to sort things but they have none on the shelf and say that Speedograph are awaiting supplies of the alloy body.
Seems a well made item however ... these are difficult times what with postal delays etc but nearly 4 months seems excessive .... fortunately I have a GPS speedo to keep me mostly on the right side of the law 🙂
