Thanks again Larry. I'm pressed for garage time now, but when I get to it, I will update my progress , or lack of it. Jim/Rott
Ok, at TCI site, they have an asterisk next to the 15 tooth drive gear on the th400 chart designating it as the one they install in thier Streetfighter transmission. Did a search for Drive gears. Found the TCI 15 tooth Drive gear at Summit. Did math: 20168/26,5=761 761×3.42×15=39039.30 39039.30/1001=39 tooth So, using the 15 tooth drive gear will save me from buying the 40-45 housing and I already have a 39 tooth Driven gear. So I can get my speedo workin correctly for $33, not bad at all if the installed Drive gear pops out easily enough.....Jim
Did the math quickly for a set of 373s I bought from Monza for possible future upgrade. Works out to a 15 tooth Drive gear / 42 tooth Driven gear combo. Ps: I have an extra Driven gear speedo housing for 34 thru 39 tooth Driven gears. I also have a NIB Blue 38 tooth Driven gear and a NIB Yellow 41 tooth Driven gear as well as what I believe is a USED White 36 tooth Driven gear if anyone needs them ......Jim
