Appriciate the effort, George!
Sounds like the same manual I got with the basket case 2L motor I 
bought.. only for 2000 cars, printed in 71...  It dosen't have a second 
value.  Maybe it dosen't have a first value either...  Just  "Bolt 
securing lower wishbone shaft to cross member, 5.5-5.9 Kgm",  which 
sounds more to me like the bolts to the crossmember of the body.  They 
aren't saying "Nut"..   This also matches with the value in the 80's 
spider factory shop manual.

Well, I realize I committed another crime.  There was some grease on the 
threads.. and that can mulitply your resulting torque by a factor of 2-3 
or more.. all the suspension specs are listed as "dry" in the Tech Spec.. 
The 95-130 ft-lbs is listed as the SAE equvilant of 5.6-5.9 kgm??  
Uh-oh, somebody blew it!!  I'll bet that's where my Kenneth Ball 
Autobook got it from... somebody didn't catch that. (whipping out 
calculator) 1 kgm should be 7.218 ft-lbs,  so 5.6-5.9 kgm is 40.4 to 
42.6 ft-lbs.

Oh well.. live and learn..  and clean and dry your threads that are 
supposed to be..  and GET THE RIGHT SPEC  if you have any question!!   
And listen to your hands...
