just wondering if a 2000 si rear mount is physically the same as a gsr.

this is the rubber not the t bracket

i know the part numbers differ. but sometimes they suercede to another number. i ordered a gsr rear mount and i got one that says 50810-sr3-000 which is a 2000 si rear mount. im just curious why the seller sent me this mount when i clearly need the st7 mount. my swap isnt lining up in my 96 integra and i think its because of this mount. should it line up anyway? someone tells me yes and others no

i searched but this particular question wasnt asked

 

anyone?

seller is telling me the sr3 superceeds the st7 mount

can anyone here confirm that a 99-00 si rubber rear engine mount fits on a dc integra?
