Guest Frank280z Posted May 16, 2000 Share Posted May 16, 2000 JTR kit with Hei dist. 1/2 from the firewall. Backed by a 4 spd Muncie. How do I measure for the driveshaft? Is it comparable to the length that the book recomends for a th350? Frank280z Quote Link to comment Share on other sites More sharing options...
pparaska Posted May 16, 2000 Share Posted May 16, 2000 With the engine and trans installed, a slip yoke slid all the way into the transmission, and the differential/driveshaft adapter bolted to the differential, measure the distance between the center of the u-joint cup hole in the slip yoke to the center of the u-joint cup hole in the driveshaft adapter on the diff. Then subtract 3/4" from that figure. That is your center-to-center driveshaft length that the fabricator needs. Quote Link to comment Share on other sites More sharing options...
Mikelly Posted May 17, 2000 Share Posted May 17, 2000 On my T56 with the JTR flange adaptor and the T400 style yoke, my drive shaft was 19 3/4 inches. Mike ------------------ "I will not be a spectator in the sport of life!" mjk Quote Link to comment Share on other sites More sharing options...
Guest mattrp Posted May 17, 2000 Share Posted May 17, 2000 Mine was also 19 3/4". I measured with about 1/2 to 3/4" extra slide in the yoke into the tranny. So i guess the swap to the t56 wont require a new drive shaft. Hehehe Matt 72 500Z Quote Link to comment Share on other sites More sharing options...
pparaska Posted May 17, 2000 Share Posted May 17, 2000 ..Mine was 19-3/4" also with the engine in the setback position, HEI 1/2" from the firewall, Tremec 5spd, Ford Yoke, and a custom driveshaft adapter. Quote Link to comment Share on other sites More sharing options...
