Looking at the online dealers there seem to be 3 sizes
standard axle
15 seater bus
heavy duty axle
I know it aint a bus so assume I have a choice of two. Am I right in thinking the standard will be the SWB and the heavy duty the LWB?
Its for this

Although if I look here and put in 1973 Transit it says I have discs which I know is wrong
