MGB Front Lower A Arm Bushing - Isn't She Pretty In Poly?

We replaced the MGBs front lower A Arm bushings as they were looking a bit ragged with bits hanging out of them.
 
Didn't have a spring compressor, so we used the "jack up the lower spring support until the A Arm is horizontal, then remove the bolts; we only did one side of the a arm at a time so that the spring and front bits would remain somewhat located:
Using a jack to compress the MGB springs - what could possibly go wrong?
We used a 1 1/8th inch socket on one side and a 15 mm socket on the other, mixing units just to be obnoxious; bushings came out without too much cursing:

Surprise! The old bushings revealed themselves to be the MGB V8 steel sleeved bushings instead of the two piece no-sleeve standard bushings.

We installed the poly bushings from Moss anyway. Note there were no metal sleeves for the interior or exterior of the bushings as is common on poly bushings - inner usually. I called Moss and they checked the kits and decided that was as it should be. I noted the greased bushings slid onto the pins with some difficulty, so there was no room for a sleeve anyway.


Working on a 45 year old car? What time is it? GRINDER TIME!!!!!!!!!!!!!  Might as well grind off the surface rust and paint with Rustoleum before remounting the parts.
Grind baby grind!

Painted and ready to return

One last note on the outside pin of the lower a arm: the grease / dust seal has a VERY thin rubber lip, which is east to fold under when reinstalling (if it happens to fall off while you are flailing and floundering trying to get the bolts for the spring pan realigned, not that it would ever happen).
