Dirttrack510 Posted June 30, 2015 Report Share Posted June 30, 2015 I posted this in my build page, but haven't got a definitive answer. .. What size and thread pitch are the bolts suppose to be that hold the transmission crossmember onto the transmission tunnel. There are four of them. They look to be size M10, but I can't seem to find the right thread. It's not helping that the bolt holes are a little rusted. Anyone know what size and thread pitch for sure? 1 Quote Link to comment
Doctor510 Posted June 30, 2015 Report Share Posted June 30, 2015 M10-1.25 sorry Mike 1 Quote Link to comment
datzenmike Posted June 30, 2015 Report Share Posted June 30, 2015 Those I believe are the cross member to transmission mount bolts although M8 X 125 are also listed on some 510s. I get... 08110-82010 M8 X 1.25 for the cross member to body 08114-02510 M10 X 1.25 for trans mount bolts. 1 Quote Link to comment
Laecaon Posted June 30, 2015 Report Share Posted June 30, 2015 Crossmember to Body is M10 for sure. Same bolts as the front bumper brackets to frame. I know because I just made a custom crossmember for my car... 1 Quote Link to comment
INDY510 Posted June 30, 2015 Report Share Posted June 30, 2015 710's use smaller bolts for the tranny X-member than 510's do ... maybe the 8mm is for 610/710s? 1 Quote Link to comment

Looking closer I see different X members for 3 and 4 speeds possibly the smaller were used on the 3 speed cross member? 1 Quote Link to comment
