[MBZ] 240D Con Rod "trim"...?

[Van Cleve]

You may remember me from such famous threads a "whats this on my 240D". 
...Thought I'd start a new one as, as I'm getting into some of the real 
meat of this rebuild. Heres where I am.......no ridge (some carbon) in the 
cylinders and NO cross hatches,  Allot of the parts in the eng look new, 
oil pump, chain tensioner & shoe, (guides). It doesn't look like its been 
too many miles since this "overhaul"  All the valves are nice and tight in 
the guides....everything looks new. Crank is a little scratched (one 
journal ), can be fixed.    One rod needs replacing and I have one thats 13 
grams heavier (19) than the "blue" one (17)  Can the machine shop trim that 
13 grams off my new rod??  The shop manual doesn't get into that . I need 
to take the crank in anyway.   Its nice to have some rain, been looking fwd 
to this shop job :-)   Thanks for looken
