Thanks Ed,

I had it professionally welded.  My late brother-in-law was to help me build it last year but cancer took him before we could get all the ducks in a row.  I could not get the mount to come together, how to cut the pieces then who could weld it.  No one near here would help and if I could not get the mount finished, the project would be abandon due a great deal to discouragement. I found an aviation welder in the Dallas area that would work with me (I due contract work in that area so am down there from Oklahoma quite often) and we got it welded in three sessions.  Took the square part directly under engine first, glued together with wood strips, then the support structure and last the two outer top braces. Not painted yet and since firewall is not complete, the reason for the grayscale picture.  If I can't get the air conditioner to clear the outer support ( it did before welding but something shifted), I might cut the top supports and narrow the rear piece to fit a standard Cozy lower cowl.  I can get the use of a cowl from a friend in Texas to use as a mold.  He is almost insistent that I go the mold method instead of custom cowl the way John Slade did.  So am grinding away on the bracket and want desperately to have a/c here in hot southwest.
