oh yeah, and are all BMX seat posts/tubes the same size?

some if not all.

again, be quiet.

and no, some seatpost are larger in diameter some are smaller.

they r different sizes the seat post on my diamondback wont fit a gt and my redline seat post is much smaller than the one on my diamondback....so yea they r different sizes, i just dont know the exact sizes for them.

most are 25.4mm (1"). the redline is probably 22.2 mmand some bmx's (possibly the diamondback) are 27.2mm

For once, he said something semi right, and you bashed him, you cant always be mean, he knew the answer, so you should chill out, if he gets something right, or doesnt say something stupid, dont bother him, maybe hes learning.

His answer was "some if not all". That's totally contradictory. Steel posts are generally all the same size. Aluminum ones come in different diameters.

so.....

i was looking at this one, but who knows.....

I think I've seen a Mongoose bike from about 1984 or something that was pretty similar to yours, I'm not sure tho.

CK0: C= Chatsworth built, 0= 1980.

I'm working on one as well, a '79 Motomag frame.

I bought a 1998 Mongoose Hooligan and I'm thinking of using it for parts to build up my 1997 Mongoose Rogue sell the frame and parts I can't use and then use the rogue parts to build up my 1997 Mongoose Sniper what should I do?
