I have found some sealed batteries at a very good price, they are simillar to odyssey but don't have the steel case . I put one in my old 33GTR in 2004 , I sold the car some years ago to a guy that I know and the Battery is still going , car has alarm and a tracker in it . I have the same in my 34 GTR and a few others in this forum have them.
I compared the specs of the battery to those of the odyssey 1200 and they appear to be almost identical in every way. Even the dimensions are the same.The only difference is the steel jacket on the odyssey.
They are 20x17x17 cm , it fits it the r33 but you need another bracket , same with the 34 GTR too.
This group buy will be open for the month of July , from the 1st to 31st. The price is $200+ delivery , about $22 registered to Melbourne and Brissy.
Anyone interested let me know via p.m. you don't have to pay up front , you pay when I get them .
