Good morning,

Thank you for the feedback and welcome :)

I had hoped that due to very similar shaft sizing of CPP and 57 Chev steering boxes that the they may be comparable in strength and fitting for a big bolt truck. (As well as simplicity of a straight swap)

As each ( 3B, gentrysgarage, & Mike B) have highlighted the CPP 500 series is for car size 1/2 & 3/4 ton.
Would using this smaller rating steering box on a 1.5 ton be acceptable if used for only cruising duties or would it be unable to turn wheels due to weight?

gentrysgarage I will contact CPP today and update with any feedback i receive,
MikeB yes my beauty is right hand drive assembled in Aus :)

Have a good one
