don't know who you're gettin parts from, but the 55.2-59 striker is not the same as the 52-55.1 .... some places don't specify with 55's, but parts should be listed like
"52-55" and
"55-59" - and the latch
52-55 -
55-59 .... close, but no cigar

with a 55 2nd you should always check against the 56 listings, not just depend on "55" - same problem with 47 1st and 2nd series
