Just ordered a bunch of bags of 92003 from American Toyota... $1.95 a bag. And the 92004 was ~$10.00 per bag. This is with the MUD discount. Not bad if you ask me....
The 92003 is 600mm in length, and the 92004 is 900mm?
You used 11 or 12 bags of the 92003 for your 60 series?
Where is the 6mm hose used?
