I got the housing from Summit and it is too small??? It's a Summit # FSS-84837 and is a Four Seasons from China. (Go figure) I'm out about $19 total. I would've thought about all the housings were the same in size but vary in hose position. Not so apparently. Maybe this is for a Yugo. It is listed as a "stock" unit. The bolt centers are 2&7/8", the hose fitting is 1&1/2" and the inner portion of the t-stat opening is 1&11/16" while the outer portion is 2&3/16".
I wonder if the LA engines have this smaller size??? I certainly did not believe that to be the case. Anybody know what this might fit? If anyone wants to buy it let me know. I can return it.
