belts

[john womble]

i received 4 belts from a distributor in GA. for my 71 280sl,  however getting the 2 belts on the AC compressor was difficult.  i have a York style compressor and the belts sent were 13x1075mm. Does anyone know if that is the correct belt size (13x1075mm) -It appears to me that the length need 1/4 or 1/2 more.  thanks for any advise...
