Werty, that looks like the 5.0 linkage to me (as far as the connection points anyway, can't see the orientation)...it's got the rubber grommit for the TV cable and the ball for the throttle cable. The SN95 linkage looks much different than that. If I find the SN95 linkage I'll snap a pic and post it.

The 70mm has done good for me (running about 9psi currently) good throttle response etc...after I get some more initial tuning done, I will be upping the boost to @ 15. At that point, I'll need more injector. The bottleneck will be the lower intake, not the 70mm TB...
If you can't get the air through (i.e. lower intake, cam, valves, heads, headers, exhaust) then it is not necessary to have an oversized TB or MAF.
Would you put a 70mm throttle body on a lawnmower? Of course not. Why? Because the lawnmower engine can only process so much air. Same concept here. If you can flow the air (if the TB is your bottleneck) then go with the larger one. If not, you are wasting your money.
There are some real good threads out there about oversizing the TB and it's effects...I think Lonnie and Jerry have written some good posts about the subject. I haven't even gotten into the potential drivability problems with MAF and TPS readings, etc, not jiving and such...
