Exact,  No one ever told me it had to be exact. :>)  It was hard because you either measure on the outside of the van or you try to mark it from inside with the heater in place and it is hard to reach & see.  I thought I marked it correctly but I was off 1/4".  The magic marker must have been out of adjustment.

I could not figure out how people get them that close, although I have seen the pics.  I did cut the lower corner of the sheet metal on the furnace but I was still out about 1 1/8".  That was close enough for me and I trimmed it with 1 1/4" door molding.  I see from other pictures, a lot of people let it stick out a bit more too.
