It can be a pain in the butt, but 4 speeds are more fun. I did a auto to manual conversion a year ago on my 66 Merc Comet and lets say I would never do it again. The way I did this conversion was I looked for the same type of car that had a 3 speed on column and got all of the parts I needed, 4 speed parts cars in boneyards are almost nonexistant. If you do it you will need the foot pedal assembly, the equalizer bar, and adjusting rods, maybe the bellhousing the yokes off of the driveshaft and the transmisson crossmember. Don't worry about buying the clutch, pressure plate,trans mount or flywheel as they are usually worn out. The driveshaft will probably have to be either lenghtened or shortened. The speedometer cable might need to be changed too. You will have to cut a hole in your floor pan for the shifter, get a shifter hump from like Sherman and Assosciates, it makes cutting the hole for the shifter easier to do. You will also need to remove the auto shifter handle if it is on the column. It took me about 5 hours to change everything over after I had the trans bolted on to the motor, and I had to make a trans mount so it might take you less time maybe more.

62-67 Chevy II's have a special block unlike other V8 Chevrolet blocks. If your block is a original Chevy II block...... not a real problem for the changeover, Just find a donor Chevy II with petals and take everything.... and I mean everything. The Z bar, all clutch linkage, throwout arm, bellhousing ect.

Someone makes a conversion kit to put the clutch pivot ball on non V8 Chevy II blocks. I have seen them...just do not remember where.


:p

Im pretty sure its not the original block. It looks like I'll have work to do. I reckon it'll be a while before I actually do it....but it'll give me some time to find a good tranny.

Thanks for the input
