I would like the change the rear gear in my 86 Toy camper,i want to try a 4.55 or a 4.37. i have found the id numbers G104 or G105 (limited slip) for the4.37 and G254 or G255 for the 4.55.Can anyone tell me what vehicles used these ratios so i can scour the scrap yards,seems it would be a hopeless task if i didnt know what trucks/cars they were originally used in. TIA Don

welcome to the forum, this will help you out alot! just read up and search craigslist or goto the junkyards and look at all the gear codes in the doors.

I have a 4:37 that came out of an automatic 4 cyl i believe. but i would check both automatic v6 and 4 cyl. If worst comes to worst i could sell you mine.
