My bro-in-law is having difficulty finding the correct Rancho 9000 series shocks for the front of his '89 LN65 Hilux. The firm supplying them has got it wrong twice now. Bit of a pain when he lives way out of town

The first set supplied were definitely the wrong end fixing type and the second set (RS99136) have only 140mm's of travel. The Blue Munroe’s that they are replacing have 180 mm's of travel.
Can anyone shed some light on the correct Rancho part numbers for a standard suspensioned Hilux LN65? Rear shock part numbers would be appreciated too. Any ideas on what the correct shock travel on the fronts and or rears should be?
I wonder if SupraLux might be able to answer this.
Thanks
John
