Can a 15100-P7A-013 oil pump from 99 civic(d16y8), be used on a d16A6 for a 91 crx Si? If not what are the differences? Only reason I ask is because i already have a new in the box OEM pump from the civic and would like to avoid buying the CRX one if they are identical or can be interchanged safely. Was unable to find spec on the two different pumps. Thank you.
