2.8 Harmonic Balancer (Help sourcing one!)

[trevorus]

Anyone know a source for these? Our 2.8 apparently has a late 70's crank in it, and the snout diameter is different from the 80's versions. We have been trying to replace the engine, and all the reman ones are proper 80's ones, but all our balancer pulleys are the larger 70's diameter. For reference, the 70's ones are 1.130 inches, the 80's are 1.100. It would be preferable to use our proper reman engine with the right balancer.
