1985 K20 Front Wheels won't engage - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I put the transfer case into 4wd. Light comes on. Front wheels won't engage. NP208 transfer case. Goes into 4 wheel low with out issue - front wheels don't engage. I think the hubs are not locking. Truck has the GM 10 bolt axle. Could the hubs be broken? Can I just put in Manual Locking hubs and if so does anyone know the best hubs for this truck. I think the Warn 20990 are the ones I need but they show up as Dana 44. Thanks.
