Has anyone replaced the oem transaxle with this gsp one, it is slightly different and I am having trouble getting the control arm bolts back in as it is almost 10mm longer on the outer side. The supplier has stated it is meant to fit and the difference is due to correcting issues with the oem one

Has anyone fitted this gsp front transaxle, it is slightly different and is about 10mm longer on the outer shaft. The supplier has stated this should fit and the difference is related to issues the oem ones had. I am having trouble getting the control arm bolts back in, is it just me or is it wrong?
