Trans shield
The CSI shield is pretty popular but I can honestly say, I wish I had a blanket over that shield. A&A makes a blanket that fits on our 727s and is a good fit. Not a universal one. The A&A is cheaper than a shield I believe and will give you more room when installing the trans in the car. The only reason I haven’t ditched my shield and went to a blanket is because my trans tunnel is removable so it makes installation easy. If you do decide to go with a CSI shield make sure you get bolts with 3/8 12 point head because a standard bolt with 7/16 6 point will cause you lots of grief when you go to put a wrench or socket on the bolt and try to tighten it.
Again, I’d recommend an A&A blanket over a CSI shield.
