The original adapters were not rotated because the bottom 2 bolt holes actually line up with the 49-64 bellhousing. This made mounting the transmission easy but the rear mount was rotated making the crossmember a pain. </P><P>The rotated version moves the shifter closer and makes the rear mount easier but makes mounting the adapter to the bellhousing a little more involved.</P><P>The pilot portion of input shaft must be shortened 1/4" so it doesn't bottom in the back of crankshaft. If the adapter is made thick enough so that the input shaft doesn't need to shortened you won't get full engagement of the splines.Mon, 30 Nov 2009 19:28:38 GMTJohn Mummerthttp://www.y-blocksforever.com/forums/Topic35097-9-1.aspxBill:</P><P>I come up with 19.05 mm, but that is a moot point because Ys are built to fractional sizes, so the related parts should be fractional also.

Geesh... now I'm gonna have to make two different spacer sets... :hehe:Sun, 29 Nov 2009 16:40:13 GMTNoobhttp://www.y-blocksforever.com/forums/Topic35097-9-1.aspxIt has been several years but recall the thickness being .750" and therefore did not need to shorten the input shaft.Sun, 29 Nov 2009 14:38:16 GMTTom Comptonhttp://www.y-blocksforever.com/forums/Topic35097-9-1.aspxCool beans, Bill... I have an empty T-5 case and tail coming next week for mock-up and now I can make some temp spacers (+/- 1/16", lol) to see whats what. I may still have to bug John, cuz I understand the new plates have a clockwise rotation to postion the shifter closer to the driver. Thanks again, Bill for the measure.</P><P>Cheers...

If anybody knows the amount of rotation his new design offers that would be great too.</P><P>I'm awaiting a gutted case and tail section so I can mock-up investigate frame and tunnel mods will be necessary before cut'n and weld'n. </P><P>Thanks in advance for any replies.</P><P>Cheers...
