Hi Max U52
The M88 entered production Feb 1961 - Feb 1964. (M88A1 was built from 1975) It was based on the M48, but was longer & narrower. There is a good write up of it by Geoffrey Tillotson in Modern Combat Vehicles 4 - M48.
You could use a M26 hull but you'd have to do a lot cutting to get the spacing right. I've started a ARV using a stretched M41 hull - 6 road wheels -
