I don't have the exact answer, but here's how I would proceed:<br /> <br /> Try dropping drill bits through the hole in the thumbrest until you find the largest one that will go through without binding. Convert that fractional drill diameter to thousandths of an inch (e.g., 5/32"=0.156").<br /> <br /> Then use a table (link) to find the closest matching wood screw size.<br /> <br /> The length you should be able to estimate by sticking a toothpick into the hole in the body to see how much goes in and adding the amount of screw that is in the thumbrest. Round the figure down to the nearest quarter inch and you should be good.

Hello Huck.<br /> Better late than never.<br /> <br /> The Fender parts catalogue for 1968 shows bass thumb rest screws as:<br /> part number 015610 "screw sheet metal oval head phillips #5 - 1 inch steel nickel plate.<br /> <br /> Out of total anorak interest,the Precision bass at that point is shown as previously using a #6 oval head wood screw by one inch,but being superceded by the #5.<br /> All of this appears to make little sense or matter that much until you compare the actual finger rests and discover that the holes in them changed in size over the years,as reflected by the note above.<br /> <br /> Stack-Knob.

super. thank you. i had planned on taking the bass to lowe's tomorrow to see if i could figure it out.<br /> <br /> and to anyone else who's pitched in with advice over the last few years, thank you, too. i just made a contribution to the site for the first time. if you're reading this and haven't contributed, please consider doing so. this is the first and best place i've found for gear info.<br />

If you have the thumb rest why take the bass? Just take the thumb rest. If it fits the hole properly, then it needs to be an inch long.<br /> <br /> As Uncle sez, oval head phillips, #5 or 6. <br /> <br /> Danny
