Hey everyone, do any of you have a web resource for sweptline and 72-93 truck frame diagrams? i need to find the front axle centerlines for both I-beam Sweptline models and 72-93 IFS ones as well. I am getting materials ready for a welder to graft an 84 front IFS frame clip to the rear of a 71 Shortbed sweptline frame. The sweptlines have the motor over the axle more than the IFS frames do. I have been on Sweptline.org already and no luck. Any help would be appreciated! I will post this in the truck section also. thanks, JP in the land of oz.
