Aligning the front half of the driveshaft with the transmission is critical to correct installation of the guibo. This tool simplifies that operation by ensuring that alignment. Bolt it in between the transmission output shaft flange and the driveshaft, make adjustments to the motor/tranny mounts and the CSB and you will have a correctly aligned drive shaft. Replace the tool with the guibo and you are finished. No eye-balling or guess work involved.
Please select either 6 Bolt or 8 Bolt Tool.
