Grilldenser!

Maybe the size of the tubes I really can’t say. I can say my 91 379 was a swamp inside even after I changed compressor, drier, condenser (went back factory) and both expansion valves. Pulled a good vacuum and recharged. In the rain you almost couldn’t stand to drive it. So I updated the condenser, and both evap cores to trucks that came with 134a and solved the problem. Mine came with a sanden compressor from the factory

 

I converted my grilldenser to a regular condenser. You will need to make up new hoses so just go ahead and change to a Sanden if you want.
You will need the condenser, 2 upper brackets, 2 lower brackets, 2 long brackets (right & left), 4 bushings, and 2 new hoses made at a shop.
Use s/n 659321. 1995 W900B. I have a 1993 W900L and put the parts on it listed for that s/n.

 

I have a 98 GM pickup and I can't get much OEM parts from dealer anymore, but can get plenty of parts for 82 W900 from KW dealer. Just something you have to work around on older equipment.

 

My 94 w900l denser failed as well. The rad shop uses a t800 condenser mount and condenser i believe. Mounted on top of the cac. Like suggested, i had to tip the rad back a touch so the bolts from the grill bars didnt rub the condenser. Both my 94 w900l now have this. Sorry I don't have any part numbers. West End Rad in Winnipeg, Manitoba is where i got the parts. They knew right away what to do.
