It seems Indy re-designed them. Not exactly sure which way round chronologically, I think maybe the later T/R's have less bolts for the top ?. It seems my memory is incorrect, mine DOES have a divider. Date on the photo's are from roughly when it was purchased and kindly sent by Todd Marsh (Sasquatch) many moons ago. Going to try this, having a 9/16 phenolic spacer machined up very soon. I fabbed up some 1/2" thick anti-reverson plates for under my carbs and also 1/2" thick delrin/nylon insulator/spacer for my tunnel ram. If you look closely it is the white portion between the intake and top plate. I made several and tried none and up to 4 spacers on dyno with no significant power or torque improvements over not having any. Choose to just use the one to help keep the top plate and carbs cooler. Hmmm....useful to know. Probably won't make any difference then, my carbs are hanging in the breeze anyway. ![[Linked Image]](http://i.imgur.com/5KFh3IA.jpg) ![[Linked Image]](http://i.imgur.com/AEcXtSn.jpg)
