Put yourself in Phil's shoes, if you had spent all that time documenting the swap you'd think that four yards would be a fair price, I think it's reasonable, and if you can't afford the manual, then you definitely can't afford the swap . Tommyd, your point is well made.

I have heard that SC400 is better to do the swap than SC3 because SC4 has SLD.

No one seems to be able to confirm for sure that all SC4's had limited slip, but it would be about another grand you wouldn't have to spend...
