P30 front suspension swap to c30?

[64swb]

I have an 87 p30 based motorhome with 30k miles on it that I may be parting out. I was wondering if the front suspension can be used on my 82 c30? the reason I ask is the 82 needs a front end rebuild as well as the fact that the motorhome has brand new 19.5 tires but it has the funky 5 lug setup in the front but regular 8 lug in back. I was thinking of changing to the P30 spindles and brakes etc if possible so I can use the wheels and tires on my c30 as well as knock out part of the front end rebuild with the motorhome parts. any info would be appreciated.
