Third Gen Coilover swap to First Gen

Got a set of practically new Bilstein 4600 Coilovers from a 3rd gen for sale locally. Are we able to swap these to a 1st gen or is there something different in the design?

 

The coils itself can fit. But I believe the coilovers are longer, and the top hat bolt pattern is different

 

I don't think the 2nd or 3rd gen coilover assemblies are in any way compatible with the 1st gen trucks. Not the least of which would be the valving and spring rate.

 

The answer is no, return em if you can

You can get the strut mount off Amazon:

But the coilover shocks are longer.
Later today I can actually take measurements. I have several sets sitting in my parts bin.
