Hi folks.
Jacques,
In comparing brake line photos, there a certainly differences in the lines. My front one was original but squashed in places. I copied off that and recreated a fairly close copy. I must admit I dont like seeing the tubing anywhere near a surface that could rub against it now or later. For that reason, I tend to add more bends to the line, to follow around raised areas, brackets, etc. That is most evident on the rear set of tubes, but the front ones have a lesser degree of the creative licence. My rear right side line does not follow around the diff hump like yours does. I'm wondering if I can rework that one to do so. Will have a look at that tomorrow. I have saved a copy of those photos for future reference. Thanks!
After roughly a week of back & forth emails to Macs, I finally got the information I had initially requested. That being the OD measurement of a shackle bolt in their 1932-1948 passenger &1932 -1947 pickup catalog. It is the correct Ford part, 01T-5780, but I have had experiences in past where I have gone from part no. alone, only to discover Ford reused the number for a subsequent civilian vehicle application, and the part was way too small.
The exact lising for the shackle bolt is: "38-47 4.28" long, 2 ton truck except 122" (6 required).......01T-5780 $9.50. This is the 1" thick bolt for Ford rear springs on 4x4 vehicles. I have no experience or info as to whether it is same for the 4x2 variants. Have now ordered six of these, along with the bolt locking pins (part no. 81T-5782) for each. I should not need to purchase bushings from Macs, because local hydraulic shop can source an extensive range of bushings. I prefer to try to support local businesses, so long as the service warrants this!
My thanks to Jacques, for supplying me with the rear spring hanger which I had been missing.

once again, the MLU community to the rescue.
