Yo! Prong! Thanks for the pics!
Here's my newly installed NP205 framemount,...took the whole weekend to discover the need, remove from the flatbed, drill the '78's frame, and install after some minor modification. FRANKENTRUCK was never supposed to have an NP205:
The short rod you've pictured is identical to my pair,...torque converter cover to engine mount rods, one each side.
FRANKENTRUCK is a '78 3/4 ton 4x4 with a 350HP 350V8 that I built, TH400/NP205 twin stick. It has a Dana 44 front axle with Warn locking hubs, and a 5560 lb rated rear axle, both from my donor flatbed. Nearing completion.
What year, and tonnage, is your truck? Todd.
