Could someone tell me the diameter of the flange that connects the propshaft to the differential? Also the PCD would be helpful aswell because when I was at the garage the other night working on my car my propshaft would not fit through my transmission tunnel , I measured the distance between the spaceframe of the transmission tunnel and it was 97mm so I think that the guy that built the chassis has made it a bit small

Thanks Mark

do a search on flange (always a funny word )someone did have a diagram all marked up with dimensions.

Are both ends of the Sierra propshaft the same?
