hiya lads...ok i have a s4c gear box "without lsd",i want to purchase a quaffe lsd ok because ive heard good reports about them ect,when i rang quaffe themselves i said to them that i had a s4c without a lsd and they said yes we have a diff here for the b series box and it will fit your box and bla bla bla.but when i was enquiring about a kazz lsd a week before that the guy i was onto said that there was 2 types of kazz diffs for the b series box and 1 was for a s4c "without a lsd" and the other was for the s4c "with a lsd"...can anybody put me straight on this as im confused im just afraid that if i give quaffe the go ahead that i will get the wrong diff ect or il have to purchase another box with a diff as standard so that the quaffe will fit i just dont want to be spending hundreds and hundreds..p.s i told quaffe that my box was a s4c without a lsd as standard and they said they have only 1 type listed anyway and it will fit my box if it has a lsd or not as standard.thanks in advance for the replys lads and sorry im not really up to scratch on gearbox info
