LS Swap lower radiator hose number

[brian mac]

I found gates number 21718 to fit perfect if the two smaller diameter 90 degree ells are cut off. This hose has the correct 1 3/4 size for the radiator connection and the correct 1 1/2 size for the ls waterpump. I am using a new 4 row replacement radiator for the 68 c10. It may be of importance to know it is 14.25" from back of core support to front of air inlet on intake. This will tell you how far forward the engine is. Maybe this info will help someone.
