I have been trying to get my hands on a replacement set of 3:90's for my VL. So I went around various wreckers and even holden spare parts in hobart trying to locate a set but was told that they are very rare and if I find a set I would be very lucky. But on this site people talk about them as if they are still in production and easy to get. What is the go? can I get a new set or do I have to reco the crown wheel & pinion? or whatever they do. Andrew. Some original photos have not been recovered yet.

Thanx, I was trying to do it on the cheap, like spend $300 max but if I cant get a 3.90 set I suppose I might have to fork out for the 3.91. does the 3.91 make much of a difference? because as it is the old girl revs at 4000rpm @ 110kph

the skyline 3.89 ones you will find whine a lot. Your better off just getting a set of 3.91 crown and pin. VLT87, wheres the best place to obtain these? Some original photos have not been recovered yet.

wouldn't mind knowing that myself! i want 3.7's but they're even more hard to come by, so 3.9's might be on the cards?

haha, yeah i got politely told by a mod that it had to go but it was fun while it lasted. macguyver is here to stay i think, his philosophy of using household objects to defuse nuclear weapons and save trapped children is pretty much in line with my thinking.
