Mudmax...where do I start;
In North America the last year for a 4 speed gear box was in 1982 and was called a L45. G52/54 gearboxes are always 5 speeds and are found only behind a carborated 22R gasoline engine from 84' to 88'. The G trans does not have a good service record and would be a poor choice behind a 2.8 5M-GE. I have only heard of two PTO gear driven t-cases and I own them both! The R150F trans is only found behind a 3.0 EFI V6 engine and always has a first generation RHD chain driven t-case. This t-case bolts to the R150F trans using nine 10x1.25 mm bolts with 14mm socket heads and has a 5 bolt rear cover. These t-cases do not have a good service record due to the heavy, wide chain, which after many miles will stretch and begin to jump teeth on the sprokets. Beging in 1996 Toyota released the 2nd generation chain driven t-case which has a lighter chain and has done very good. These t-cases are LHD and have eight 8x125 mm bolts with a 5 bolt rear cover.
Toyota makes two 9 bolt transmission to bellhousing bolt patterns. Small pattern; G52/54 (84-88 22R Carb), G58 (89-95 22R EFI), W56 (85-95 22R EFI), and big pattern; (86-87 22R EFI Turbo), (88-95 3.0 EFI V6). To bolt the R150F trans to your 5M-GE motor, you need a 86-87 R151F bellhousing. This has a 22R (same has the 5M-GE block), and the larger R bolt pattern. I sell a used bellhousing for $150.00. Both transmissions use the same input shaft length, pilot, and release bearing and will bolt right up. You can bolt the stronger gear driven t-case behind the R trans but you will need my V6 adapter plate (349.00), and a 23 spline turbo input gear (165.00)
Hope this helped    Marlin
