Title: Firewall holes for vac lines?
Post by: RogerArrick on October 04, 2011, 11:30:27 AM

At the top of the firewall there are 2 holes, one for the heater valve vac control line, and the other for the AC cannister vac line. 

Is there suppose to be grommets there?  If so I can't find it listed in the parts catalog.  Or did it just have sealer blobbed around it originally?

Roger - just in case there are differences - When and where was your car built?

Makes searching all the pictures easier and the answer more correct for your needs ;)

Looked and looked through about 2000 pictures (didn't want to compare the other two plants ;) unfortunately not an often pictured location and the cowl pinch  weld gets in the way ( as well as providing a big shadow)

Anyway - not conclusive IMHO will look at some cars tomorrow at the shop to see if there are any 68 SJ AC cars

I think there's suppose to be a grommet there instead of caulking.  The hole is 5/8".  Haven't found them in any catalog.

5/8 is a rather large hole but I have never seen grommets used there. Marty
