Hi Rick, Nice work on the Diamond T, it looks great!
I toughed-out building the 968A Cargo Open Cab just this past winter for the ‘Lend Lease Campaign.’ As you and others have mentioned — ginormous sprue gates at every turn!
— love/hate during much of the build. … Though I must admit, some of my frustration was my own doing for not sticking to the original plan to build OOB.
I did find the instructions to be rather foggy during the latter third of the build — was wondering if your experience was the same. One thing that literally gave me nightmares was the radiator-to-hood-to-cab-to-frame alignments — lots of fiddly dry-fitting to get it right! 
Ultimately, I’d have to say, I loved the kit more than hated it. Good quality, high parts-count value and an excellent challenge as well.
Looking forward to more of your build.
Cheers!
