Okay so I have 1987 Camaro Z28 with a 5 speed manual transmission. My old shift plate was broken and shift boot worn , so I decided to buy a pretty good condition shift plate from eBay . It just arrived and I noticed the metal bracket they use to hold the boot to the plate is different and won't fit on the replacement plate any info on the proper bracket I need or what years it's for would be appreciated. New on left old on right
New shift plate numbers
Original shift plate numbers
The bracket

 

Is it close to fitting? Could you drill some new holes and make it work??? I may get some metal stock and fab one up with a jig saw!

...or scour ebay.

...and for the record, my 89 is definitely like the one on the left. NOT like your 87. Not sure about 88.
