I am quite sure that it is the Type 70-1.
It would seem you are correct that road wheels match the YW 534 . However, the shape of the hull is (particularly the bluntness of the glacius) is YW 531.
It would seem that depending on your source, this vehicle in my picture is alternately labeled ...
Type 54: http://www.fas.org/man/dod-101/sys/land/row/type-54-sph.htm or
Type 70: http://www.jedsite.info/fulltrack-tango/tango-type/type-85_series/type-70-2/type702-intro.html
Jane's confirms that even Type 70 is built on YW 531:
The first model (WZ 302 or Type 70) was based on the chassis of the Type B531 and still fitted with only four road wheels. The WZ 302A (also known as the Type 70-1) and the WZ 302B (also known as Type 70-2) have the longer chassis of the YW 531H but with the old diesel engine and with the commander's position front right. The WZ designator indicates that this was only built for the PLA.
Of note, Jane's does not have an article on the type 54-1 SPH, but at a few points within the Type 70 SPH article it describes it as "type 54-1" and at one pont mentions the "Type 54-1/Type 70-1." There is also mention of a Type 70-2. Both the -1 and -2 variants are described as being based on the YW 531H.
This leads me to believe that, despite mention of the Type 54 SPH on FAS & Jed, that Type 54 SPH is Type 70 SPH with the name of the gun (Type 54-1) mistakenly used as the name of the system.
