heres an email from a company
Hi David
Anything is possible, depends on how much you want to spend? Initially I will give you a price on what we already manufacture-
1st-2nd Straight cut Syncro gear set- $2640
3rd Straight cut Syncro gear set- $835
4th Straight cut Syncro set- $835
1st-2nd Straight cut dog gear set- $3300
3rd-4th Straight cut Dog gear set- $2200 (includes billet steel 3/4 selector fork)
3/4 Billet Chrome moly selector fork- $385
Heavy Duty Final Drive- $1870
(All prices inc GST)
To change the gearbox to a sequential 6speed is a very time consuming process. To do 1off you would be looking at around $25,000, 5off around $22,000 and 10off around $20,000. Of the other items I have listed here we have most of them in stock.
Regards,
Simon
